The 80120 is a parabolic reflector with a gold coating that enhances IR reflectance. Off-axis parabolic reflectors collect radiation from a source at its focal point and reflect it as a collimated beam, parallel to the axis. Alternatively, they can tightly focus a collimated beam at its focus. The focal point is off the mechanical axis, giving full access to the reflector focus area. There are no shadowing problems if a detector, fiber or source is placed at the focus. Off-axis parabolic reflectors provide very efficient radiation control since focus or collection is over very large solid angles. This makes them particularly useful for lower power incoherent light sources. The 80120 is integrated into the Oriel^® 80007 and 80009 IR light sources, as well as the 80033 and 80040 Fiber Couplers. The 80120 is offered separately for those who wish to use it for focus or collection.
