The Uniblitz MS150B is a 150mm bi-stable shutter suitable for large scale imaging systems or where a large optical path needs to be reduced to zero transmittance. The shutter’s lifetime is around 500,000 cycles – high for an aperture of its size – and its blades are low mass, highly emissive, and positioned to avoid collisions during operation. With the on-board drive circuit, a user must only provide a +12VDC power supply and a pulse width determined (+5V TTL) exposure pulse.

Bi-stable shutter devices, like the MS150B, require no power to hold the blades in either the open or closed state.

Shutter Timing


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.
