BSI High Sensitivity Fiber Spectrometer M series
M Series BSI High Sensitivity UV Enhanced Spectrometer (Backside Illuminated) utilizes Hamamatsu area array backside-illuminated CCD, and its UV sensitivity is increased by about 7 times compared to an ordinary spectrometer. At the same time, it uses 280 & 760nm double blazed grating, equipped with LVF anti-high-order filter, based on a 100.0mm focal length optical platform. It provides a balanced sensitivity and higher resolution in the full spectrum of 200~1100nm, which is suitable for a variety of Spectrometers for scientific research applications.
| Key Product Highlights Peak 70% UV response - utilizes Hamamatsu back-thinned CCD and have over 70% quantum efficiency in the ultraviolet 200nm, which is very suitable for Broad-spectrum measurement including ultraviolet band;
64x2048 Super large sensing surface super-large sensing area CCD, which sensitivity is further improved by 4 times as compared to the ordinary 14-line pixel CCD; 200-1100nm Full spectrum coverage- M Series use optical platform with a focal length of 100.0mm which is suitable for full spectrum detection at 200~1100nm, covering the entire photosensitive area of the detector while increasing the resolution by 10%. |
