Dual Spectrometer extended range systems
The Dual Spectrometer (DS) Series integrates two spectrometers into a single compact system, enabling continuous coverage from UV to NIR (180–1700 nm). Using a Y-splitter fiber and robust Czerny-Turner optical design, the DS Series delivers high resolution, low stray light, and fast spectral response across a broad wavelength range. Its modular structure allows pairing of UV-VIS or VIS detectors with NIR detectors with a common trigger, offering flexible configurations tailored to diverse research and industrial needs.

Series Concept
- Dual Engine Design: Combines one UV-VIS/VIS spectrometer (SE/EE models) with one NIR spectrometer (SW models). The system has a single trigger.
- Extended Spectral Coverage: Up to 180–1700 nm with seamless overlap between VIS and NIR channels.
- Flexible Pairing: Users can choose combinations (e.g., DS2686 = EE2060 + SW2860).
Models and Configurations
- UV-VIS Options (SE/EE Series): 180–1100 nm (CCD/CMOS, optional TE-cooled back-thinned CCD)
- NIR Options (SW Series): 900–1700 nm (InGaAs, optional TE cooling)
- Dual Combinations: Configurable pairing of one UV-VIS and one NIR model
