Thorlabs Introduces Line Of Lightweight, Compact Motorized Actuators

Newton, NJ, May 1, 2002 Thorlabs Inc., a leading manufacturer of innovative photonics products, announces the introduction of a new family of affordable Motorized Actuators. These Motorized Actuators offer accurate, high-resolution motion control and placement for precision processes such as fiber-optic alignment and positioning. Compared with similar Motorized Actuators, they are easier to control and offer better price-to-performance ratios.

This new series of actuators are offered in 6mm, 13mm, and 25mm travel lengths. Two mounting options, 1/4-80 threads or 3/8" mounting shoulder, allow these actuators to be direct drop-in replacements for manual adjusters in most translation stages and optical mounts.

The compact design of these actuators, combined with a powerful 12V miniature DC motor allows for quick, precise adjustments in most applications. A high-resolution rotary encoder provides 12,288 counts per revolution at the lead screw resulting in a 0.2µm minimum incremental movement. Electromechanical limit switches prevent over extension of the actuator. All of these features combined together in a lightweight package at a fraction of the cost of comparable models make these actuators ideal for automating almost any application.

Thorlabs engineer Jason Mills commented, "I think our customers will find these compact actuators surprisingly powerful."
