Uniblitz® CS45
45mm Uni-Stable Optical Shutter

Overview

Key Features

The Uniblitz CS45 has been designed to provide accurate, repeatable••

Large 45mm aperture

exposures for a wide variety of applications such as telescopy and••Uni-stable operation

aerospace. The slim form-factor provides a large 45mm aperture••

5-bladed designthat can be inserted into a 4.00 inch diameter housing. The CS45••

Slim form-factor

is available in a housed or an un-housed configuration for OEM••

RoHS Compliantapplications (or simply where spatial limitations are a consideration).

••Transfer time on opening:
14.0 milliseconds

Uni-stable shutter devices, like the CS45, require power to hold theblades in the open state.

the driver utilized) after the shutter transfers to the open state. The system
incorporates an infrared emitting diode, an infrared sensitive detecting
transistor, and an interrupting vane. The vane is attached to the shutter so
as to block the light path between the emitter and detector in the closed
position. When the shutter transfers to the 80% open position, the vaneis removed from the infrared light path, allowing the emitter to switch theGND

detector to the active state. For the CS45, this system uses a similar activation
