The Uniblitz NS45B is a 45mm-aperture bi-stable optical shutter utilizing our patented N-CAS® technology. The NS45B’s simple design provides maximum clearance around the aperture, and a machined flat surface makes for its easy integration into telescopes, video cameras, etc. The NS45B has an overall diameter of 3.915 inches, and an electronic synchronization is available.
Bi-stable shutter devices, like the NS45B, require no power to hold the blades in either the open or closed state.
For additional technical information please see the NS45B Optical Shutter Datasheet.

1 Two 12 OHM coils wired in parallel
2 Peak voltage as provided by the VED24 Driver
3 (Continuous/Burst) Continuous frequency rating specified at shutter’s minimum exposure pulse. Burst frequency rating specified for four (4) seconds maximum with one (1) minute minimum between bursts.
The question regarding enhancement of shutter speed with the application of user supplied lubricants has been repeatedly asked. It is our experience that lubricating the shutter blades will actually slow the shutter down and eventually render the shutter inoperable. Under no circumstances should any type of lubricant be applied to the shutter blade area.
