Most of our light sources produce UV radiation; the arc and deuterium sources produce very intense ultraviolet. Exposure, even for short periods of time, can cause severe skin and eye burns. It is best to shut off the source when it is not in use. When this is impractical because of frequent use, these safety shutters provide a reliable alternative. The shutter enclosure mounts to the condenser output of any Oriel Light Source, and closes off the beam. You can also use these shutters for timed exposures (the shutters do not have "bounce" problems). TIME (20 ms INCREMENTS) SHUTTER CLOSING WITH FULL COLLIMATED ARC LAMP BEAM FILLING APERTURE. SHUTTER CHARACTERISTICS WITH HeNe THROUGH THE CENTER ACTUAL OF THE APERTURE. TTL PULSE SHUTTER OPENING LIGHT THROUGH SHUTTER Fig. 1 The open and close times depend on the shutter speed and the beam power distribution. For this figure we used a 1.5 Inch Series, F/1.5 condenser on the output of our arc lamp housing. The second trace shows the open and close characteristics of the same 71445 Shutter with a ~ 1 mm HeNe laser beam. • Terminate beam without shutting down the system • Usable with sources to 1000 W • Convenient remote control switch Specifications Input 95 - 130 VAC/0.25 A, max 190 - 260 VAC/0.125 A, max Output Hold, Open* 12 VDC, nominal 0.5 A, nominal Output Hold, Close 0 V, 0 A * Initial opening V and A are higher.
