The 80033 is an ideal choice when transitioning from a collimated beam of light into a fiber (or visa versa) when working in the infrared. Its 1.5-Inch Series female flange is compatible with a variety of products, including the Oriel^® FT-IR Spectrometer Modular solution. 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. There is no shadowing with the fiber positioned at the focal point. An advantage of the 80033 is that it can accept a variety of fiber terminations. Simply select the appropriate fiber adapter, screw it into place, connect the fiber and adjust its position along the X-Y axis for maximum throughput. Interchangeable fiber adapters are available for SMA, ST and 11 mm ferrule terminations (ordered separately). This type of reflector provides very efficient radiation control because collection or focus occurs over very large solid angles. This makes the 80033 particularly useful with lower power incoherent sources, such as the 80007 Silicon Carbide or 80009 QTH infrared sources.
