How They Work • Turning a single knob tilts the optic with slight translation. In our gimbal mounts there is a 2.5-µm translation for a 1° tilt. For our conventional mounts, one degree of tilt results in 0.35-mm translation.

• Turning all three knobs an equal amount results in pure translation along the optical

The sapphire seats and other design innovations used in our precision mounts result in true kinematic positioning. Using sapphire as the bearing surface for our ball-tipped screws ensures that repetitive adjustments do not leave tracks that make positioning nondeterministic. Also, our 1/4-80 screw sets are made with great precision, so very fine adjustments can be made consistently.

If you’d like to see for yourself, try the “snap” test with one of our mounts in your lab. Put the mount in an interferometer and “snap” the mount joints by separating them and letting them snap back. This will give you an indication of the quality of the construction of the mount. With sapphire seats, thicker frames, and stiffer springs, our mounts should return to the same starting position, which will translate into excellent thermal stability.

Optical Modulators & Choppers

Then, to ensure the mounts have exceptional long-term stability, we use a proprietary screwassembly process with very tight tolerances to minimize slop. We limit the amount of grease in the actuators to reduce migration over time and from temperature variations. This results in mounts with very smooth movement and high precision, as well as exceptional long-term and thermal stability. In our commercial versions, our unique lock system allows us to maintain this smooth feel without adding grease or increasing costs. Just compare one of our screws with one from another company—you’ll notice the difference right away.

Compare any of our mounts to comparably priced versions from our competitors and you’ll find that we have the thickest frames. Even our tiny mounts are made of stiff stainless steel to achieve greater stability for their size. The graphs to the right show our mounts compared to the competition. The graph on the top shows that our mounts have a smaller deflection for all applied forces so your experiment will be easier to align. The graph on the bottom shows that as an impact force is applied to the mounts, our mounts remain in place while the others misalign.

Detectors, Receivers & Power Meters

When we design our mirror mounts, we strive to make mounts that provide precision adjustments that really stay put. To give you the ultimate in precision, one of our design criteria is to approach the textbook definition of kinematic—where there exists precisely one constraint or actuator for each independent degree of freedom. That’s why we use a cone-vee-flat configuration. To provide even more precision and durability, we use sapphire seats to ensure that repetitive adjustments do not leave tracks that would make positioning non-kinematic, and therefore non-deterministic and imprecise.

Mirror Mount Selection Guide We know how important stability and repeatability are—both in the research environment and on the manufacturing floor. That’s why our opto-mechanical components provide superior stability, high resolution, and precision adjustment capabilities. We offer a full line of optic mounts, from the economical Valu™ mounts to our most stable Classic line. Each offers the thickest frame in its class for the highest stability. We also offer specialty mounts such as the Flipper™ mounts, the Opti-Claw™ mounts, prism mounts, and top mounts. With over 10 years of designing and building some of the most stable opto-mechanical components on the market, we’re able to bring you the very best.

Mount Families All our mounts are designed to be kinematic. We use sapphire seats and three ball-tipped 1/4-80 screws to kinematically position the front plate. One screw is seated in a cone, the second in a V-groove, and the third against a flat. Because the cone gives three points of contact, the V-groove, two and the flat, one, the plate is held in exactly six places, and thus is kinematic. The hard, smooth, sapphire seats prevent the balls from denting the surface, reducing friction. This translates into mounts with superior stability and durability. Classic: Our original mounts that offer superior stability at a great price. Valu™ Mount: Our most economical mounts that offer you the best performance for your dollar. These mounts have two adjustment screws, while the Classic mounts have three. Ideal for when cost is an issue. Commercial: Ideal for industrial applications (and laboratory too), these mounts offer two adjustment screws, extra-stiff springs, locks and two mounting holes per side. Stability™ Mount: These mounts provide the ultimate in stability. Their unique optic-retention system minimizes wavefront distortion while maximizing stability. Pint-Sized: These mounts are only half the size of our Classic mounts, yet can still hold 1/2" and 1" optics.

Mount Styles We offer a variety of kinematic mounts so you can find one for your application. Center and corner mounts are offset by 1" in our English version and 25 mm in our metric versions in both the horizontal and vertical directions. This allows corner and center mounts to be used together in the same setup by simply taking a “step” on an optical table. Center: The traditional style where the optic is in the center of the mount. Turning one screw results in slight translation. Corner: Our original design where the optic sits in the fourth corner of a square defined by it and three adjustment screws. With corner mounts, you get tilt, tilt without translation (turn two adjacent knobs an equal amount), and pure translation (turn all three knobs an equal amount). Blank: Blank mounts have four threaded 8-32 (M4) holes so you can mount that unusual optic. Or use the mounts horizontally as a low-cost tip-tilt stage. Gimbal: These gimbal mounts deliver increased stability and true tilt without translation Opti-Claw Mount: The claws of the unique Opti-Claw mount are shaped and cammed so that the center of any optic (from 1/8" to 2" diameter) is the same distance from the table, eliminating the need to adjust the height when you want to use a different diameter optic. Top: Perfect in tight situations when you need all adjustments easily accessible from the top without worrying about blocking your beam. Flipper Mount: A traditional mirror mount on a hinge so you can easily move the optic into and out of the beam path. Prism: A flat platform for holding prisms and beamsplitters. Unique clamp eliminates messy double-stick tape or red wax.

Tiny: Truly compact, stainless-steel mounts that hold 1/2" optics. Vacuum-compatible, too.

Mounting—Your Key to Stability The way you mount your optics can make the difference between a stable setup and one that suffers from vibrations. When building a setup, be sure to minimize beam height, use fewer parts (for instance, use a single post or pedestal rather than stacking them), and use parts made of thick, stiff material such as steel. We offer two different mounting systems for your experiments—posts with post holders and pedestal risers. Posts with post holders are the more conventional alternative and are particularly convenient because they offer continuous height adjustment. Pedestals, on the other hand, offer significantly more stability because of their wider diameters, but are available only in fixed heights. (For those in-between heights, try our Model 9950 pedestal shim set.)

much better stability than conventional post holders that only lock with a screw. However, even this may not be stable enough for all applications. As shown in the graph, the pedestal system shows much less deflection than a post for a given force, due to the pedestal’s larger diameter and increased stiffness. A stiff mounting system will make your optics easier to align, and will also perform better when excited by acoustic vibrations. Added benefits of our pedestal system include a flange integrated onto the base and a relieved seat for extra-stable longterm mounting. Our fork system allows you to mount a pedestal anywhere on your optical table.

These two mounting systems react differently to forces such as vibrations or the force of your hand when making adjustments, which can affect your experiment. This motion becomes apparent during alignment of your optical system. The amount of motion caused by your hand during alignment is determined by the stiffness of the post or pedestal.

Technical Note

How to Get the Best Thermal Performance from Your Mounts Whether you are a laboratory researcher or an optical-equipment manufacturer, you’ll be concerned with how temperature changes affect your optical system. A stable mount will lead to improved optical-system performance as the ambient temperature changes. For example, the power stability of a laser made with stable mounts will be better than that from a system composed of inferior mounts. Not only should you be concerned with changes over only a few degrees (as exists in a laboratory) but also, you may want to understand how the system will perform through many decades of temperature variations (as exists in the field). And, if you are shipping the equipment, you will be concerned with survival conditions that exist while the equipment sits in an airplane, on a truck, or on a train. In this case, a mount free of hysteresis will result in a turn-key system that will not require realignment upon arrival.

often use stainless steel. However, it is important to note that aluminum has a significantly higher thermal conductivity and is therefore good for applications that require dissipating heat quickly, such as to avoid thermal gradients that cause significant distortion.

• Mirror-Mount Configurations: In order to minimize irreversible shifts leading to unwanted drift, the design of the mount is important. For instance, the bladed flexure mount has the worst thermal stability because the flexures, the most critical element in the mount, have relatively small thermal mass and are subject to changes in environmental temperature. As the flexures heat and cool, they do so non-uniformly, causing distor-

Design Issues to Minimize Thermal Drift In order to minimize drift due to thermal effects, it is important to consider not just the materials used but also the design of the mount and the joints.

• Materials: Thermal expansion causes a change in the size and shape of parts. A material’s thermal property is characterized by the coefficient of thermal expansion, α, where the change in size, ∆L, is related to a temperature change, ∆T, by ∆L= α L ∆T (L is the length of the component in that direction). Therefore, the amount of change depends upon the size, material and temperature variation. The most common materials used to make opto-mechanical components are aluminum, brass, and stainless steel. As listed in Table 1, aluminum is twice as sensitive to temperature changes as stainless and brass. This is why applications requiring interferometric stability

Different mounts fill different needs. Illustrated are: (a) vee, cone and flat mount; (b) three-vee mount; and (c) flexure mount.

also need to consider the length of each actuator or adjustment screw. If they differ in length (such as in a top-actuated mount) then you’ll get some distortion because each will expand different amounts. (Standard mirror mounts will always be more stable than top mounts, because the extra mechanism to turn the screw action through 90° will yield kinematic ambiguity and hence instability.)

• Joints: In addition to understanding the effect temperature variations have on materials and specific design configurations, it also important to understand how joints perform when the temperature changes. Temperature variations cause irreversible shifts in position from the fluid flow of grease and the unrelieved stress in kinematic seats. The ideal joint thus should minimize grease and have low friction, thus little stress. In a low-friction joint, each ball is uniquely located in its cone, vee, or flat seat. The restoring force of the spring pulls the mount plate as far as possible into the seats where it is kinematically seated in its unique resting point. If, however, there exists high friction, such as when there’s some roughness in the seats, the balls will not have a single and final resting point. If there’s some slippage due to temperature, creep, shock, or vibration, the component will move. In this case, the component is no longer truly kinematic and will suffer from long-term instabilities. Thus, a good joint will have sapphire seats or hardened steel pads to reduce friction.

tion. The best mounts are those employing true kinematic design principles (the condition where there exists exactly one constraint or actuator for each of the six independent degrees of freedom). There are two types of kinematic mounts—the “vee, cone and flat” mount and the “threevee” mount. (See figure.) In all cases, you

The proprietary precision 1/4-80 screws give you increased durability, better repeatability, and even more precise adjustment than comparably priced mounts.

Optical Modulators & Choppers

Because the optic sits close to the edge of these mounts, they are ideal for setups where clearance is an issue. We offer our corner mounts with different optic mounting holes to accept English and metric mirror diameters.

Motion Control

By centering the optic at the fourth corner of the square formed with the three adjustment screws, you get tilt, tilt without translation, and pure translation—all in a single mount. For pure translation, simply turn all knobs the same amount. (A 1° error in one knob results in only 0.0012° tilt in the face plate.) For tilt without translation, use two knobs, or for applications when translation is less important, adjust the tilt with just one knob.

Top-Actuated Mounts • Top- and side-mounting options • Low cost • Lockable design

These mirror mounts are ideal for use in compact spaces. They give you easy access to both tip and tilt adjustments from the top without worrying about blocking the beam. Through careful mechanical design and attention to details, we’ve minimized the hysteresis commonly found in other top mounts. These mounts have hardened seats and greater resolution than any other mounts of their type. Top- and side-mounting schemes are compatible with post and pedestal mounting systems. Relieved bases and thick frames ensure stability, while standard beam heights allow for easy integration into your system. Built-in locks and stiff springs increase long-term stability.

• Easily flip optics into and out of your beam path • Kinematic design gives you 200-µrad repeatability • Lockable

Optical Modulators & Choppers Motion Control

We created our Flipper™ mount by adding a hinge to a traditional optic mount. The result is a mount that lets you move an optic into and out of your beam path easily and repeatably. Ideal for turning mirrors in multiplexed laser experiments, this mount eliminates many of the headaches associated with sharing a laser. Adjustment screws let you steer your beam, while a sapphire pad under the screw gives you better than 200-µrad repeatability between flips. A 2" (50-mm) version complements our popular 1" (25-mm) size.

These 1/4-80 precision screw sets (used in our optic mounts) allow you to build your own mounts or positioners. Our proprietary assembly process uses very tight tolerances and allows us to use very little grease. We limit the amount of grease because over time, and as the temperature varies, large amounts of grease can cause the threads to migrate, leading to hysteresis as well as long-term creep. The result of our proprietary process is actuators that have very smooth, wobble-free movement, high precision, and exceptional long-term and thermal stability.
