Agilis Optical Mounts– Newport’s piezo motor driven optical mounts take a completely new approach to the adjustments needed for many laser setups. Agilis Mounts provide the ultra-high adjustment sensitivity and convenient, safe and remote operation of a motorized component in the size of a manual mount!
Why Agilis Optical Mounts?
Mechanical friction and the effects of a person's touch limit the precision of many optical adjustments. In theory, it is possible to achieve sub arc-sec adjustment sensitivity with very fine mechanics and differential screws. However, in practice, the lateral forces applied to a component during an adjustment often have an excessive effect, making alignments lengthy and frustrating. Also, many optical experiments are extremely sensitive to environmental factors and provide consistent results only when isolated properly against external influences.
Motorized mounts overcome the limits of manual components, but are typically costly and bulky, restricting their use for systems integration or simple remote operation in tight spaces. Agilis mounts are a lower cost solution in a miniature size and do not compromise adjustment sensitivity, speed, or position stability.
Agilis optical mounts are the first products that feature Newport’s proven, proprietary, non-resonant piezo direct motors. These highly integrated motors are directly coupled to the moving platen. When idle, spring forces lock the mirror’s position for true set and forget long term stability. Agilis mounts have a faster adjustment speed than alternative screw driven designs and are free of the problems associated with backlash or hysteresis. In contrast to ultrasonic motors, the Agilis non-resonant motors enables small adjustments to be more predictable. With its 50 nm minimum incremental motion capability, Agilis mounts are ideal for ultra-sensitive optical alignments.
For repeatable absolute positioning, the AG-M050L and AG-M100L feature precision electrical limit switches. These switches act not only as safety devices, they also allow repeatable absolute positioning without the need for expensive encoder feedback. This is accomplished by measuring the average step size from the left to the right travel limits and vice versa. Under consistent conditions, the step size is fairly repeatable. Together with high level commands integrated into the Agilis™ Motion Controllers, , it is possible to register and return to a set position with better than 0.05° repeatability, anytime and anywhere. 0.05° repeatability is approximately equivalent to 1/12 of a turn of a micrometer screw on a manual mount of comparable size.
