Overview


The Uniblitz DSS25B is a 25mm-aperture bi-stable optical shutter that has eliminated the external protruding actuator and contains no other interfering components. This makes the DSS25B an extremely low-profile device that is capable of fitting into very tight spaces. Additionally, the device’s flat mounting surfaces make for its easy integration into virtually any system.

Bi-stable shutter devices, like the DSS25B, require no power to hold the blades in either the open or closed state.

 

Key Features


  • 25mm aperture
  • Bi-stable operation
  • Only two unique moving parts
  • Extremely slim, low-profile form-factor
  • RoHS Compliant
  • Transfer time on opening: 12.6 milliseconds
  • Total opening time: 25.8 milliseconds
  • Configured for the VED24 Shutter Driver

Shutter Timing


timing-diagram-white


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.
