CS65H 65mm Optical Shutter


Current Lead Time: 4 – 6 weeks


Click to view the CS65H datasheet, which features mechanical and electrical specifications, timing data, and technical drawings.

The Uniblitz CS65H has been designed to provide accurate, repeatable exposures for a wide variety of applications such as telescopy and aerospace. For 2022, the CS65 has been upgraded with dual actuators to significantly improve the shutter speed and reliability (“CS65H”). The slim form-factor provides a 65mm aperture that can be inserted into a 5.00 inch diameter housing. It’s available in a housed or un-housed configurations for OEM applications.

Uni-stable shutter devices, like the CS65H, 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.

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. Additionally, the 5-pin female mating connector (5F) is no longer included with purchase.

*The “For use in Vacuum” option will equip the shutter with encapsulated coils for vacuum levels up to 10-10 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.
