Product Details

制冷型近红外光谱仪

The refrigeration type near-infrared fiber spectrometer adopts imported high-performance gratings/900-1700nm and 900-2500nm near-infrared spectroscopy/modularity/good thermal stability

CME-NIR1700 and CME-NIR2500Refrigeration type near-infrared spectrometerIt is a portable spectrometer with thermoelectric internal cooling technology. This series of spectrometers adopts a linear arrayInGaAs CCD detector greatly improves the spectral acquisition speed; Unique C-T cross optical path design to achieve high-resolution optical platform.

Widely used in various fields, such as transmittance and reflectance measurement, irradiance, absorbance and concentration measurement, color measurement, concentration measurement of chemical composition or radiometric analysis, film thickness measurement, gas composition analysis, protein, biological research and other fields.

Product advantages:

1. Adopting CT non cross symmetric optical path effectively reduces stray light and improves system resolution;

2Smaller and thinner in size, more convenient to integrate into devices;

3High anti reflective cylindrical mirror, stronger signal;

4Rich optional accessories including light sources, fiber optics, and CCD probes;

5Chip level refrigeration with higher signal-to-noise ratio;

6Integrate the GPIO interface of Zhongke Weineng, making it convenient for users to obtain data through USB, serial port, and SPI;

7Provide a secondary development toolkit with development package functionality *, support for hot plugging, and support for simultaneously controlling the entire spectrum of spectrometer products from Zhongke Micro Energy Instrument. After adding references, users can directly call functions to implement various functions. Customer programming languages support C #, C/C++, Java, Delphi, Matlab, Labview, VB, VBA, Python, etc.
