Explorer NIR, 256pixels InGaAs near-infrared spectrometer

Explorer NIR-256 Explorer NIR-256

The Explorer NIR-256 near-infrared spectrometer is designed to use Hamamatsu's uncooled 256pixels InGaAs sensor. Compared with the 128 pixels sensor, the number and size of pixels are doubled, allowing the highest resolution to be 1.5nm. The optical platform of this series of spectrometers adopts a replaceable slit design. One spectrometer can be configured with a variety of slits of different widths to meet the spectrum measurement needs of different resolutions and sensitivities. The optical machine is small in size and flexible in configuration. It is very suitable for fields such as near-infrared LD detection, food testing, biopharmaceutical and scientific research, and industrial integration.

Product advantages：

Using Hamamatsu 256pixels uncooled InGaAs sensor, the highest resolution reaches ~1.5nm.
Compact optical path and structural design, suitable for system integration.
It has an interchangeable slit design that can be matched with slits of different specifications. Users can choose different resolutions and sensitivities to meet the needs of experiments.
The wavelength range and resolution can be customized to configure the appropriate spectral range and resolution.
Professional measurement software, providing measurement functions such as absorbance/transmittance/concentration/reflectivity/timing monitoring.

Applications：

Measurement of near-infrared LD light source spectrum
Food and agricultural testing, such as sweetness and freshness testing of vegetables and fruits; fat and protein testing of meat; moisture testing of grains and seeds, etc.
Oil composition analysis
Biopharmaceutical online monitoring and process analysis
Plastic sorting
