Any substance is characterised by a certain temperature expansion coefficient and responds to temperature variations by either expanding or decreasing its physical Proportions. Therefore, thermal expansion of optical aspects might change a system’s optical overall performance resulting in defocusing as a result of a change of temperature.
Employing a very trusted closed cycle cooled MWIR INSB or HOT MCT detectors, the Defender Long vary imager delivers Extraordinary extended vary general performance with detection of human targets beyond thirty kilometers and motor vehicles past 40km with specialty F4 optics.
A Cooled Mid-Wave Infrared (MWIR) lens is A necessary part in thermal imaging devices meant to work throughout the mid-wave infrared spectrum, which frequently handles the wavelength vary from roughly three to five microns.
