Features

Quartz Tungsten Halogen (QTH) Infrared Light Source

The 80009 is a complete quartz tungsten halogen (QTH) infrared light source that provides a smooth continuum from 14,000 to 2,800 cm-1 (0.7 to 3.5 µm). Its 1.5-Inch Series female output flange allows the source to be coupled to a variety of items, including the FT-IR Spectrometer Building Blocks. An off-axis parabolic reflector is integrated into the design, rather than a condenser lens. IR refractive optics are expensive and have transmittance limitations. Using this type of reflector provides several advantages. Its gold coating enhances IR reflectance. The focal point is displaced from the mechanical axis, giving full access to the reflector focus area. The 80009 produces a 34.5 mm (1.36 inch) diameter collimated output beam with 1° divergence, full angle. A hose fitting is provided to purge the source with nitrogen, if desired. The 80009 includes a 20-watt QTH lamp and a stand-alone power supply designed to minimize light ripple. A 1 m (3.3 ft.) long cable connects the source to its power supply.

Silicon Carbide (SiC) Infrared Light Source

The 80007 is a complete silicon carbide (SiC) infrared light source that provides a smooth continuum from 6,000 to 400 cm-1 (1.7 to 25 µm). Its 1.5-Inch Series female output flange allows the source to be coupled to a variety of items, including FT-IR Spectrometer Building Blocks.
