ES6B 6mm Laser Shutter


Current Lead Time: 5 – 6 weeks

Guaranteed Lifetime: 25,000,000 Cycles


Current Lead Time: 5 – 6 weeks

The Uniblitz ES6B is a 6mm bi-stable laser shutter with a very low-profile construction and guaranteed lifetime of 25,000,000 actuations. Its lack of an external protruding actuator makes it very slim and flexible for system integration. Precision exposure control and laser switching are applications that benefit greatly from the precise, highly repeatable characteristics of the ES shutter series.

Bi-stable shutter devices, like the ES6B, 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.
