ST50S (90; 100) Transmission imaging spectrometer

Short Description:

JINSP ST50/90/100S series transmission imaging spectrometers are the ultimate high-performance spectrometers for weak signal detection.
ST50/90/100S series spectrometer adopts VPH volume holographic phase grating, the diffraction efficiency of the grating is as high as 80%~90%, which is slightly higher than reflection grating. The optical path is designed with a high numerical aperture and zero optical aberration, which can achieve the best collection efficiency and theoretical limit resolution. At the same time, it is compatible with mainstream scientific research-grade deep cooling cameras such as PI and Andor, thus ensuring excellent quantum efficiency and dark current noise.
SR50/90/100S series spectrometers can receive SMA905 fibre input light and free space light, At the same time, it supports multi-core fibre and multi-channel, and is compact and portable. It is very suitable for spectral detection in scientific research directions such as materials and biology and industrial detection of low-concentration samples or weak signals.
