NS25B 25mm Optical Shutter
⠀⠀⠀⠀⠀⠀⠀⠀⠀
Description
Current Lead Time: 4 – 5 weeks
The Uniblitz NS25B is a 25mm-aperture bi-stable optical shutter utilizing our patented N-CAS® technology. The NS25B’s simple design provides maximum clearance around the aperture, and a machined flat surface makes for its easy integration into virtually any system. The NS25B has an overall diameter of 2.250 inches, and an electronic synchronization is available.
Bi-stable shutter devices, like the NS25B, require no power to hold the blades in either the open or closed state.
*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.
