The 80021 InSb detector exhibits superior performance over its operating range and approaches the maximum theoretical limit of sensitivity for background-limited applications. This detector requires liquid nitrogen cooling. Liquid nitrogen holding time is eight hours. A preamplifier is integrated into the design, which reduces the effects of background radiation. It is matched with the detector, allowing the detector to function at its ideal operating point. A manually adjustable iris is included with the 80021. Its diameter range is from 0.8" to 1.4" (2 to 36 mm). The iris can act as a Jacquinot Stop. By decreasing the effective source size and reducing the spot size on the detector, resolution is increased. The iris uses standard Oriel 1.5-Inch Series male and female flanges, allowing it to be easily integrated into the FT-IR system, if desired.

80021 InSb探测器在其工作范围内表现出优越的性能，并接近极限灵敏度的理论极限，适用于有限背景的应用。这个探测器需要液氮冷却。液氮保持时间为8小时。设计中集成了前置放大器，降低了背景辐射的影响。与检测器匹配，使检测器在理想的操作点上工作。80021配有手动调节虹膜。其直径范围为0.8“至1.4”(2至36毫米)。虹膜可以作为按摩器的停止部分。通过减小有效源尺寸和减小探测器上的点尺寸，提高了分辨率。虹膜采用1.5英寸标准腔的内外法兰，如果需要，可以很容易地集成到FT-IR系统中。
