CS35

OVERVIEW

The CS35 is the fifth release in the new UNIBLITZ®CS series.  The small form factor allows a 35 mm aperture to beinstalled into applications not presently accessible with existing UNIBLITZVS series shutters. As with the CS25, CS45, CS65 and CS90, the CS35 hasbeen designed to provide accurate, repeatable exposures for a widevariety of applications.  The small form factor allows a 35 mm apertureto be installed into a 3.33-inch diameter housing (a 30% reduction inoverall size from the VS35 series). To increase the unit’s flexibility,the shutter can be supplied in an un-housed version for OEMapplications or in situations inaccessible to most shutters due tospatial limitations.

The UNIBLITZ®CS35 incorporates a new actuator system that can be driven withexisting VMM drive units. As an option, the shutter may also beequipped with an electronic synchronization system, to increase theunit’s flexibility. It is available in a housed or un-housed OEMversion that is electronically programmed to fire specific exposures atprecise time intervals. The new shutter’s multi-bladed design, combined with its new UNIBLITZ actuator, provides increased reliability over other designs of this type.

When gating high intensity light sources, the CS35 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 furtherenhance the flexibility of the CS35; an optional #100 mounting ring isavailable to allow the shutter to be easily mounted in manynon-specific applications. Additional mounts available can be found inthe specific data sheets entitled “MICROSCOPE, VIDEO and UNIVERSALMOUNTING SYSTEMS” or on-line under “products”, “Mounting Systems”.

Electrical

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

² Dual hold voltage level driver system included in UNIBLITZ^® VMM/VCM shutter controller.

Mechanical

¹ CONTinuous frequency 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.

The question 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 CS35un-housed style is the basic configuration of this device and is bestsuited for OEM applications. Mounting can be accomplished throughthree 0-80 (flat head screws required) clearance holes located aroundthe unit’s perimeter on a 2.995 inch diameter bolt circle.  Unlessotherwise specified, this standard unit is terminated to a 5-pin maleconnector through a 5-wire six-inch cable assembly.

Housed Style

The CS35#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 CS35, the #100 Mounting Ring isa mounting option available that simplifies mounting the housed styleonto a flat surface. Additional information regarding the #100 mountingring  can be found in the specific data sheet entitled “MICROSCOPE,VIDEO AND UNIVERSAL MOUNTING SYSTEMS” or online under “products”,“Mounting Systems”. A removable spacer ring is also included with thisdevice. This ring allows mounting of all standard microscope mounts. Inaddition when adding the #17 “F” mount, this ring is removable allowinglens back clearance. This ring is secured into the housing with three0-80 flat head screws.   The unit terminates with a 5-pin maleconnector as illustrated.
