The latest photonic solutions

The optical system of the GL SPECTIS 8.0 is using the latest technology solutions available in spectroscopy. Mirror/Grating/Mirror spectrometer platform uses silica transmission grating and back thinned CCD image sensor. The sensor and electronics are thermally stabilized and the software is constantly monitoring the base line level. Transmission gratings provide supreme transmission properties and high diffusion efficiency. These characteristics allow to set a very short integration time which is important in high accuracy light sources measurements and can be the crucial factor in ultra-fast production process control applications. Back thinned CCD sensor offers very high quantum efficiency over the wide spectral range. This helps to achieve more accurate and low noise light measurements in the UV, VIS and NIR range. The high optical resolution of this platform makes it an ideal tool for narrow band light sources measurements and fast light measurements in industry applications.
