CS90HS 90mm Uni-stable Shutters

OVERVIEW
The CS90HS is presently the largest aperture in the UNIBLITZ® CS series and is an upgrade from the CS90S. This
new upgrade improves performance, increases reliability, increases operating speed and eliminates the on-board
secondary actuator driver utilized in the CS90S version. The small form factor allows a 90 mm aperture to be installed
into applications not presently accessible with existing UNIBLITZ®VS series shutters. As with the CS45S and CS65S,
the CS90HS has been designed to provide accurate, repeatable exposures for a wide variety of applications. The small
form factor allows a 90 mm aperture to be installed into a seven-inch diameter housing. To increase the unit’s flexibility,
the shutter can be supplied in an un-housed version for OEM applications or in situations inaccessible to most shutters
due to spatial limitations.
The device incorporates a dual actuator system. Both actuators operate simultaneously allowing the shutter to be
controlled with existing UNIBLITZ® drive units. As an option, the shutter can be equipped the electronic
synchronization system.
When gating high intensity light sources, the CS90HS can be equipped with polished stainless steel reflective blades –
on special order. This option protects the shutter blades from the light source’s damaging effects by reflecting the
energy away from the blade surface. Look for future availability of “Z” (AlSiO) and “ZM” (AlMgF2) coated blades in this
device.
To further enhance the flexibility of the CS90HS; an optional #103 mounting ring is available to allow the shutter to be
easily mounted in many non-specific applications. Additional information regarding the #103 mounting ring can be
found in the specific datasheets entitled “MICROSCOPE, VIDEO, or UNIVERSAL MOUNTING SYSTEMS” or online
under “products”, “Mounting Systems”.
