ST90S Transmission Imaging Spectrometer

Short Description:

The JINSP ST90S transmission imaging spectrometer is equipped with VPH volume phase holographic transmission grating, with a diffraction efficiency of 90% and excellent light path.The advanced featured spectrometer can reach sensitivity five times greater than that of are flective spectrometer, and its resolution is twice as high as that of conventional spectrometers, resulting in a perfect spectrum detection effect. Additionally, it is paired with a high-quality deep-cooling CCD array camera designed for standard research applications, ensuring excellent quantum efficiency and a high signal-to-noise ratio.

The ST90S is well-suited for 532nm laser Raman spectrum detection systems, particularly in the context of gas Raman signal detection. With exceptional optical properties, a spectrum range of up to 4200 cm^-1, and a resolution of up to 4 cm^-1, it can replace large imported reflection spectrometers used for scientific research. Furthermore, it has excellent stability and compact size, making it ideal for integrating industrial equipment.
