The 71446 Electronic Safety Shutter consists of a 2 Inch Series flanged enclosure that houses the blade, and a stand-alone shutter drive for 115 and 220 V operation. The enclosure has a female-flange on one end and a male-flange on the other. The male end couples directly to the light source condenser and the female end accepts any male flanged accessory. The clear aperture for a through beam 1.9 inches (48 mm) for 2 Inch Series condensers. You can also rod mount the shutter in the light path. A 1/4-20 tapped hole in the bottom accepts our optical rods. The shutter drive has an open/close switch and a TTL or contact closure input so you can control the shutter via a PC. Note: a computer cable is not supplied - a standard LPT cable is needed for interfacing. These shutters also have an interlock socket adapter so you can wire one to your lab door and have the shutter close every time the door opens. The rise/fall time of the blade is ~0.1 second (see Fig. 1), but there is a delay before the blade starts to close the aperture. The front of the supply has an LED to indicate whether the shutter is open or closed. A 5 ft. (1.5 m) power cable connects the shutter to the driver. For faster open and close times, use the shutter at the focus of a lens and with a small aperture. You can then recollimate the output with a second lens. If output intensity is not critical, you don’t have to focus and then recollimate the beam, just use an aperture between the condenser and the shutter.
