CS90H 90mm Optical Shutter


Current Lead Time: 6 – 8 weeks


Click to view the CS90H datasheet, which features mechanical and electrical specifications, timing data, and technical drawings.

The Uniblitz CS90H has been designed to provide accurate, repeatable exposures for a wide variety of applications such as telescopy and aerospace. The slim form-factor provides a very large 90mm aperture that can be inserted into a 7.00 inch diameter housing. The CS90H is available in a housed or an un-housed configuration for OEM applications (or simply where spatial limitations are a consideration). For 2023, the CS90H has been upgraded with a 5-pin connector. A 501A-S7 Shutter Adapter Cable is required for use with VMM-D3, VMM-D4, D880C and any VCM-D1 purchased prior to November 2022. The 501A-S7 is not included with the purchase of a CS Series Shutter.

Uni-stable shutter devices, like the CS90H, require power to hold the blades in the open state.

A normally open configuration of this device is available by special order. Please contact us for more information.

*The “For use in Vacuum” option will equip the shutter with encapsulated coils for vacuum levels up to 10-6 Torr. The housing, connector, and electronic sync options cannot be selected from the product builder when “For use in Vacuum” is applied as these options are not vacuum compatible and may cause outgassing. For higher vacuum-rated applications, or questions, please contact us.
