Motion Control – Laser Beam Steering Voice Coil Stage is Gold Plated!

Santa Clarita, CA — Gold plated Voice Coil Linear Positioning Stage designed for a laser beam steering application features high acceleration and high resolution. This high acceleration compact VCS Series stage from H2W Technologies has a stroke length of 25 mm (1.0 in.) and a positioning resolution of 1 micron (0.000004 in.) The low mass, zero cogging, moving coil has very low electrical and mechanical time constants allowing for high acceleration/deceleration of light pay loads such as steering mirrors. These stages are ideal for short stroke, closed loop, applications requiring high resolution, and high acceleration /deceleration control. Typical beam steering applications include: Laser pointers and designators, Obstacle avoidance systems, Free space optical communications, Laser micromachining, and in Manufacturing, Aerospace, Medical, and Defense industries.

This compact Voice Coil Stage measures 95.3 mm (3.75 in.) long X 111 mm (4.37 in.) wide X 89.4 mm (3.52 in.) high and features a continuous force rating of 8.9 N (2 lbs) and peak force of 26.7 N (6 lbs) with a payload capacity of .91 Kg (2 lbs). For closed loop operation the stage features a high resolution non-contact linear encoder.

Standard H2W Technologies VCS Series of Voice Coil Stages are available with: Travel lengths from 1 mm (0.04 in.) to 75 mm (3.0 in.), Resolution from .0.1 micron (0.000004 in.) to 12 microns (.0005 in.), Acceleration from 0.1 to 10 G’s, Continuous force from 1 N (0.25 lbs) to 444 N (100 lbs), and Peak force from 3 N to 0.75 lbs) to 1333 N (300 lbs). VCS Stages are available with custom drilled and tapped holes, custom leads and connectors, as well as components that are gold plated, anodized and hard coated. Additionally, completely custom stage are available with very short lead times.
