High Sensitivity Micro Spectrometer
SSP-27 is a micro spectrometer with high sensitivity and high transmittance. It adopts more efficient optical bench design, which makes its sensitivity 3-4 times higher
than routine micro spectrometers. It uses a large numerical aperture optical design, which can accept all photons in the optical fiber (numerical aperture 0.22). This makes it
especially suitable for the analysis of low signals, such as gas analysis Raman spectrometers, fluorescence spectrometers, etc.
