Line Sensor – InGaAs linear detector
Line Sensor, or InGaAs linear sensors, are actually detectors for SWIR spectroscopy applications. While Silicon-based sensors, such as CMOS, PDA and CCD are not sensitive from 900nm to 2.5µm, InGaAs linear detector can do the job. InGaAs sensors: These are like special cameras that see infrared light, which is light we can’t see with our eyes. Uncooled and TE-cooled packages: They come in two versions: one that works at normal temperatures, and one that’s kept cold to work better. High sensitivity: They can see very faint infrared light. Low readout noise: They produce clear images with less “static” or interference. High frame rates: They can take many pictures very quickly, like a fast movie. Good linear response: They accurately measure the amount of infrared light.
NIR absorbance/reflectance applications:
This means they are used to see how materials absorb or reflect infrared light. Conveyor belt plastic sorting and recycling: They can help sort different types of plastic on a moving belt. Moisture content measurement: They can tell how much water is in food and animal feed. Hyperspectral and medical imaging: They can create detailed pictures for scientific research and medical diagnoses.
