华北光电技术研究所近期研制成下述两种红外探测器: 1.碲锡铅异质结红外探测器 这是以碲锡铅晶体作衬底、用液相“异质结”外延技术制成的红外探测器。响应波长为8～12μm,适于室温目标的探测、成象。可应用于红外前视、医用热成象、遥感、跟踪、污染监控等方面。该器件的探测率D一般大于1×10~(10)cm·Hz 1/2/W,最高的D≥4～5×10~(10)cm·Hz 1/2/W;峰值波长λ_p≥10μm。经
North China Institute of Optoelectronics Technology recently developed the following two kinds of infrared detectors: 1. Tellurium tin lead heterojunction infrared detector This is made of tellurium-tin-lead crystal substrate, using liquid “heterojunction” epitaxial technology Infrared detector. Response wavelength of 8 ~ 12μm, suitable for detection of the target at room temperature, imaging. Can be used in infrared foresight, medical thermal imaging, remote sensing, tracking, pollution monitoring and so on. The detection rate D of the device is generally larger than 1 × 10 ~ (10) cm · Hz 1/2 / W, the highest D≥4 ~ 5 × 10 ~ (10) cm · Hz 1/2 / W; the peak wavelength λ_p≥ 10 μm. through
