LBTEK's Near-Infrared Fiber Optic Spectrometer utilizes a two-stage cooled InGaAs detector, making it suitable for spectral detection and analysis in the near-infrared wavelength range. The LBTEK Near-Infrared Spectrometer features a compact structural design and employs chip-level internal cooling technology, effectively reducing dark noise while achieving higher signal-to-noise ratio and significantly improving weak light detection capability. LBTEK provides the LBSpectra control software specifically developed for spectrometers, allowing users to perform routine operations on spectral curves through the software. When paired with various spectral application kits available on the LUBANG Mall, it enables the measurement of parameters such as reflectance and transmittance. Additionally, with the dedicated chromaticity dynamic library, users can easily and quickly achieve the measurement and application of CIE standard colorimetric parameters.
