Overview


The Uniblitz CS90 has been designed to provide accurate, repeatable exposures for a wide variety of applications such as telescopy and aerospace. The slim form-factor provides a very large 90mm aperture that can be inserted into a 7.00 inch diameter housing. The CS90 is available in a housed or an un-housed configuration for OEM applications (or simply where spatial limitations are a consideration).

Uni-stable shutter devices, like the CS90, require power to hold the blades in the open state.

A normally open configuration of this device is available by special order. Please contact us for more information.

Electronic Synchronization System


The electronic synchronization system provides a feedback signal (through the driver utilized) after the shutter transfers to the open state. The system incorporates an infrared emitting diode, an infrared sensitive detecting transistor, and an interrupting vane. The vane is attached to the shutter so as to block the light path between the emitter and detector in the closed position. When the shutter transfers to the 80% open position, the vane is removed from the infrared light path, allowing the emitter to switch the detector to the active state. For the CS90, this system uses a similar activation flag attached to the mechanism, which triggers a reflective emitter/detector device. No connection to the designated synchronization pins when no electronic sync. is selected.

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.
