WebbCooling an array detector with a built-in thermoelectric cooler (TEC) is an effective way to reduce dark current and noise, as well as to enhance the dynamic range and detection limit. When the InGaAs array detector is cooled from a room temperature of 25°C down to -15°C by the TEC, the dark current is reduced by ~32 times and the dark noise ... WebbInGaAs linear sensors are detectors for SWIR spectroscopy applications, where CCD, PDA and CMOS silicon-based sensors are no longer sensitive, from 900nm to 2.5µm. …
Introduction to Scientific InGaAs FPA Cameras
WebbSince then, the development of InGaAs, InSb, and HgCdTe detectors has facilitated ground-based observations in the J and H astronomical bands of the NIR-II / short-wavelength infrared (SWIR) range extending from 1050 nm to beyond 1700 nm. The J and H bands, which are depicted in Figure 1, correspond to 1100–1400 nm and 1500–1800 … WebbInGaAs detector arrays are a combination of detector material, which detects the light and turns the photons into electron-hole pairs. The number of electron-hole pairs is … dogfish tackle \u0026 marine
