Explorer NIR-512

Explorer NIR-512

The Explorer NIR-512 near-infrared spectrometer is designed to use Hamamatsu's uncooled 512 pixels InGaAs sensor and an optimized optical-mechanical platform, resulting in a maximum optical resolution better than 1nm, making it very suitable for the detection of near-infrared LD light sources. 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. Small in size, 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 512pixels uncooled InGaAs sensor, the highest resolution reaches ~1.0nm.
  • 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.
  • Measurement of near-infrared LED 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
