Quest Series Spectrometer
The NIR Quest is a versatile NIR spectrometer for applications ranging from moisture detection and chemical analysis to high-resolution laser and optical fiber characterization. NIR Quest spectrometers cover the wavelength range from 900-2500 nm.
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.
