Spectral Products is offering the new SM642 non-TE cooled Back-Thinned 2048pixel array CCD spectrometer. The SM642 provides high quantum efficiency in UV and high dynamic range. The detector used in the SM642 HRS has 2048 pixels and helps to get better resolution. It is ideal for UV/VIS/NIR spectrometry that requires high signal to noise ratio and/or high dynamic range. The back-thinned CCD has excellent sensitivity in UV and allows deep UV application, even below 200nm. Well designed housing allows up to 75nm measurement window within 200~1050nm for 0.2nm optical resolution with very low stray light. The Back-Thinned detector to measure very low light signal by reducing the noise level in long integration time.
