Uniblitz® CS35
35mm Uni-Stable Optical Shutter

Overview

Key Features

The Uniblitz CS35 has been designed to provide accurate, repeatable••

35mm aperture

exposures for a wide variety of applications including microscopy,••Uni-stable operation

video imaging, and more. The slim form-factor provides a 35mm••

501A-S7 adapter included

aperture that can be inserted into a 3.33 inch diameter housing. The••

Slim, small form-factor

CS35 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:13.0 milliseconds

Uni-stable shutter devices, like the CS35, require power to hold theblades in the open state.
