CS25 25mm Uni-stable Shutters

Overview
The CS25 is the fourth release in the new UNIBLITZ®CS series. The small form factor allows a 25 mm aperture to be
installed into applications not presently accessible with existing UNIBLITZ®VS series shutters. As with the CS45, CS65
and CS90, the CS25 has been designed to provide accurate, repeatable exposures for a wide variety of applications.
The small form factor allows a 25 mm aperture to be installed into a 2.37-inch diameter housing (a 40% reduction in
overall size from the VS25 series). 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 UNIBLITZ® CS25 incorporates a new miniaturized actuator system that can be driven with existing VMM drive
units. As an option, the shutter may also be equipped with an electronic synchronization system, to increase the unit’s
flexibility. It is available in a housed or un-housed OEM version that is electronically programmed to fire specific
exposures at precise time intervals. The new shutter’s multi-bladed design, combined with its new miniaturized
UNIBLITZ® actuator, provides increased reliability over other designs of this type.
When gating high intensity light sources, the CS25 can be equipped with reflective blades. This option protects the
shutter blades from the light source’s damaging effects by reflecting the energy away from the blade surface. Three
standard reflective blade options are available. “S” (reflective stainless steel), “Z” (AlSiO) and “ZM” (AlMgF2).
To further enhance the flexibility of the CS25; an optional #100 mounting ring is available to allow the shutter to be
easily mounted in many non-specific applications. Additional information regarding the #100 mounting ring and
additional mounts available can be found in the specific data sheets entitled “MICROSCOPE, VIDEO or UNIVERSAL
MOUNTING SYSTEMS” or on-line under “products”, “Mounting Systems”.
