 Advantages of the NIR Quest Spectrometer

Reliable, robust spectrometer with deep thermoelectric cooling down to -20 °C for low dark current
Fast data transfer – great for applications with chemo metric models
Configurable with a range of detectors, gratings and slits for your specific application
Replaceable slit design and optional internal shutter.
The models are available in two different ways: custom configured and preconfigured.
Our preconfigured spectrometers are optimized around specific NIR applications. We offer preconfigured spectrometers for optimum response within a specific wavelength range.
