18-Bit Deep-Cooled Spectrometer DQplus, ≥36000:1 Dynamic Range (CAT#: STEM-AL-8914-ZJF)

The DQplus is an 18-bit deep-cooled spectrometer intended for high-dynamic-range cooled spectroscopy. It is designed to acquire low-noise spectra with high dynamic range and selectable grating/slit configurations. The optical, electronic, or mechanical configuration uses a two-stage cooled area detector with 100 mm focal length, selectable gratings, slits, filters, and fiber interface. Operation is based on deep-cooled 18-bit spectral acquisition with optional long-pass and order-sorting filters. The design supports the source-listed measurement or handling functions without adding unsupported capabilities. The product can be integrated into laser, lamp, Raman, and general high-dynamic-range spectroscopy. The stated performance, interfaces, and operating limits are restricted to the information provided in the source. Overall, the product provides a dedicated platform or component for high-dynamic-range cooled spectroscopy.
