The new performance standard in NIR spectroscopy
The highly sensitive InGaAs line sensors with 256, 512 or 1,024 pixels from Polytec’s partner Sensors Unlimited are available with upper limit wavelengths of between 1.45 µm and 2.6 µm. New manufacturing processes give rise to top results in NIR absorption spectroscopy or Raman measurements due to further reduced dark current and improved homogeneity.
You can choose between two readout variants: “integrate then read” with the LBD / LE array or “integrate while read” with the the LC array. The LC version in particular, with its four programmable gain options, is perfect for integration in fast vision systems and high-resolution spectrometers.
