Infrared Light Source, 9 W IR Emitter, Q Series Housing

Three different IR light sources are available, varying in the type of IR emitter included. An IR emitter should be chosen based on output intensity and radiating area.

• 6575: This 22 W IR Element has a spectral irradiance very similar to a Nernst element. Like the 6363, its shape and mounting position make it easy to align with the input slit of a monochromator. 
• 6363: The uniform emissivity over a large radiating area, shape, and mounting position of this 140 W IR Element makes it easy to align with the input slit of a monochromator. 
• 6580: A 9 W element useful for its small, but efficient radiating area of 0.14 in2. This is the most inexpensive option of the three IR emitters offered.

A 50331AU and a OAP-ADAPT are included with these IR light source kits for optimum optical output. The 50331AU is a gold coated, off-axis parabolic reflector, while the OAP-ADAPT provides the mounting solution. This mirror provides a large light collection angle and high reflectance over a wide wavelength range, without the chromatic aberrations lenses often contribute to an optical output. Unlike on-axis parabolic and ellipsoidal reflectors, the off-axis configuration places the optical axis and focal point of the mirror away from its mechanical axis. This blocks stray light from the output path of the light, simplifying the placement of detectors and other associated hardware.

The 60000 Series Q Lamp Housing contains four output ports. These output ports can remain plugged if unused, or fitted with a condenser lens assembly. If a different optical output assembly is mounted to each output port, four simultaneous light outputs, each of a different wavelength emission and profile characteristics can be achieved using a single light source.
