SideWinder NIR Spectrometer

The SideWinder (SW) Series spectrometers are designed for long-wavelength near-infrared applications, built with high-sensitivity InGaAs linear sensors and a 32-bit RISC processor for precision control. The compact, rugged optical engine is optimized for stability and performance, maintaining exceptional resistance to thermal, humidity, vibration, and shock variations to minimize wavelength shift and resolution drift. Covering wavelength ranges from 900 nm to 2500 nm, the SW Series offers both non-cooled and TEC-cooled models for enhanced noise reduction and extended integration times. Powered via USB with 6 programmable I/O lines, the SideWinder Series integrates easily into research, process-control, and OEM systems requiring reliable NIR performance.
