CS25

The CS25 is the fourth release in the new UNIBLITZ®CS series. The small form factor allows a 25 mm aperture to beinstalled into applications not presently accessible with existing UNIBLITZ®VS series shutters. As with the CS45, CS65 and CS90, the CS25 has beendesigned to provide accurate, repeatable exposures for a wide varietyof applications. The small form factor allows a 25 mm aperture to beinstalled into a 2.37-inch diameter housing (a 40% reduction in overallsize from the VS25 series). To increase the unit’s flexibility, the shutter can be supplied in an un-housed version for OEM applications orin situations inaccessible to most shutters due to spatial limitations.

The UNIBLITZ® CS25 incorporates a newminiaturized actuator system that can be driven with existing VMM driveunits. As an option, the shutter may also be equipped with anelectronic synchronization system, to increase the unit’s flexibility.It is available in a housed or un-housed OEM version that iselectronically programmed to fire specific exposures at precise timeintervals. The new shutter’s multi-bladed design, combined with its newminiaturized 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 thelight source’s damaging effects by reflecting the energy away from theblade 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 mountingring is available to allow the shutter to be easily mounted in manynon-specific applications. Additional information regarding the #100 mounting ring and additional mounts available can be found in thespecific data sheets entitled “MICROSCOPE, VIDEO or UNIVERSAL MOUNTINGSYSTEMS” or on-line under “products”,“Mounting Systems”.

Electrical

¹ Voltage level required across actuator coil when being held in the open position.

Mechanical

¹ CONTinuousfrequency rating specified at shutter’s minimum exposure pulse. BURSTfrequency rating specified for (4) four seconds maximum with (1) oneminute minimum between bursts. Frequency measurements are taken infree air, 25°C ambient, actuator coil equipped with heat sink. Foradditional information on maximum sustained frequencies obtainable,please contact one of our technical representatives.

Timing

The following chart lists typical timing values (msec.)using UNIBLITZ® drive equipment and measured with UNIBLITZ® shuttersequipped with standard black Teflon® coated shutter blades.

Thequestion regarding enhancement of shutter speed with the application ofuser supplied lubricants has been repeatedly asked. It is ourexperience that lubricating the shutter blades will actually slow theshutter down and eventually render the shutter inoperable. UNDER NOCIRCUMSTANCES SHOULD ANY TYPE OF LUBRICANT BE APPLIED TO THE SHUTTERBLADE AREA

Unhoused Style

The CS25un-housed style is the basic configuration of this device and is bestsuited for OEM applications. Mounting can be accomplished through four0-80 (flat head screws required) clearance holes located around theunit’s perimeter on a 2.120 inch diameter bolt circle. These holes, asindicated, are 72 degrees apart. Unless otherwise specified, thisstandard unit is terminated to a 5-pin male connector through a 5-wiresix-inch cable assembly. (The five 2-56 holes and one 0-80 hole are notrecommended for mounting due to the potential for interference with theshutter’s five blades or actuator mechanism.)

Housed Style

The CS25#3 housing style allows a number of mounting configurations. A ¼-20threaded hole is provided for post mounting. The 1.625inch x 40TPIexternal thread located on the rear side, and the specific mountingholes located on the front side (see Figure #2 and Figure #3) can beinterfaced directly into your application or fitted with a variety ofuser specific mounting options. For the CS25, the #90 Mounting Ring isa mounting option available that simplifies mounting the housed styleonto a flat surface. In addition, the CS25’s standard #3 housing covercan be replaced with a cover containing a one inch manually variableiris diaphragm. The overall housing thickness will increase by .150inches (3.8mm) when this option is specified. The #90 mounting ring canattach to this cover in the same manner as the standard cover.Additional information regarding the #90 mounting ring and the #52525mm Variable Iris can be found in the specific data sheet entitled“UNIVERSAL MOUNTING SYSTEMS” or online under “products”, “MountingSystems”. The unit terminates with a 5-pin male connector asillustrated.
