NIR-SWIR spectrometer
- very compact (mini or micro spectrometer): 52 x 57 x 17 mm
- designed for industry
- research-grade quality
- wavelengths between 800 and 2100 nm
….but excellent for benchtop and academic use as well.
Key Features of the MAP-Siena compact spectrometer in the SWIR (well some people call it also NIR):
- wavelengths up to 2100 nm and down to 800 nm
- Miniature size; some people call them micro-spectrometer or mini-spectrometer: 52 x 57 x 17 mm
- uncooled InGaAs sensor
- built-in dark current compensation: no need for fan or cooling even up to 2100 nm: strong reduction of size and very low power consumption
- high sensitivity / low stray light
- More affordable than ever: we do not offer cheap or low cost spectrometers but we can call them budget or economical spectrometers given their low price compared to their great value.
The Siena takes near-infrared spectroscopy in the NIR / SWIR to a new level. It combines the performance and flexibility of an array-based spectrometer with the size, price and reliability required for mobile applications, OEM and industrial sensors. For the first time it offers wavelength ranges up to 2100 nm with an uncooled InGaAs array sensor.
SWIR spectrometers are usually either high-performance or low-cost. The MAP-Siena delivers the technical performance for precise measurements at a price suitable for integration in portable and industrial sensors or OEM applications. Large absorbance values can be accurately measured due to its superior sensitivity, optimized stray light suppression and high dynamic range. The MAP-Siena opens up countless new possibilities for NIR/SWIR-based sensors.
