Featuring variable frequency from DC–25 Hz, Model CH-62 consists of blade mounted on motor with limited rotation angle. Current in one direction will set chopper to open position, while current in other direction will set chopper to close position. In internal mode, CH-62 is used as variable low frequency chopper with frequency set by internal oscillator adjustable from 1–25 Hz. In external mode, CH-62 is used as chopper or shutter and is controlled by external TTL signal input up to 25 Hz.

Optimized for non-uniformity correction and filter changers in defense applications, Nanomotion Shutters feature direct drive piezo technology with closed loop control, delivering silent operation and low EMI/RFI profiles. Mechanical design creates closest back-working distance and does not conflict with footprint of video assembly. Housed in 8 x 20 mm package weighing less than 2 g, shutters provide 35–120° travel and are suited for in-flight, head-mounted, or handheld devices.
Laser Shutters provide multimillion-cycle operation.

Based on rotor drive actuation technology, SafeClose™ Laser Shutters maintain safe laser conditions by closing automatically when power is interrupted. Units feature fail-safe magnetic blade return mechanism and gold-plated blade design for high laser damage thresholds. Other optional blade coatings are available to meet specific laser line performance requirements. Operating from -40 to +70°C, shutters offer shock and vibration resistance and do not require separate controller.
Optical Shutters handle extreme environmental conditions.
