| | | How to Choose an IR Detector Wavelength, sensitivity, speed of response and active area are the main parameters you need to consider when choosing the detector. Optimal Wavelength, Spectral Range Typical spectral responses were presented in the glossary. Our standard detectors are optimized for any wavelength within 3-13 um range. Additional optical filters or special device heterostructures can be used to achieve selective devices. Sensitivity The detectivity is the best parameter to characterize detector sensitivity. The higher the D*, the better the detector. The better performance cost both money and complexity of the system. The higher performance can be achieved with optical immersion (Series names with "I") and thermoelectrical cooling (-2TE and -3TE series). Typical D* are shown in table on the page 8. Speed Of Response Our uncooled and thermoelectrically cooled detectors can be used for both low and high frequency applications. Uncooled photoconductive devices can provide very good service at medium frequencies up to hundreds of megahertz. They are limited by 1/f noise at low frequencies. Photovoltaic and photoelectromagnetic detectors are the devices of choice for operation from DC to very high frequencies, even exceeding 1 GHz for some custom devices. Faster response speeds can be obtained by applying reverse bias to photodiodes. Compare time of response x and choose the best solution for your application. Active area Standard squared active areas are specified in data sheet for each device. | | Applications Our devices can be found in various applications. The detectors can be optimized for work with any YAG, QC and C02 industrial lasers. The most typical applications of the VIGO System S.A. detectors are given below: | | |
