Offering a combination of high quantum efficiency, wide dynamic range and ease of use for photon counting applications, the Count Blue from Laser Components provides everything needed for photon detection towards the blue end of the spectrum. Photon detection efficiencies of 60 per cent are readily achieved in the blue range and 65 per cent in the green and yellow, making these modules some of the most competitive on the market for shorter wavelength detection. These modules combine Laser Components’ ultra-low noise avalanche photodiodes with specially developed quenching and processing electronics to deliver a powerful solution for detecting single photons.
Finding application in confocal microscopy, particulate sizing, fluorescence analysis, Lidar, astronomy and Raman spectroscopy, the Count Blue can be provided with an optional FC fibre connector for even greater versatility.
