●High reflectivity featuring more than 98% reflectivity in the wide spectrum range of UV - VIS - NIR (200 - 2500nm)

●Excellent Lambert - type reflector with a flat spectral in the range of UV - VIS - NIR

●Using PTFE material with good chemical stability, not easy to release powder and become yellow

●In the ultraviolet-visible-near-infrared (200-2500nm) wide spectral range, it has high reflectivity (over 98% in the full spectrum) and is a Lambertian reflector with a flat spectrum

●Made of PTFE material, it has good chemical stability, and is not easy to release powder or turn yellow

●It can be used in various scenarios such as spectrometer reflectivity calibration, coating and color reflectivity testing, covering fields like optical detection and aerospace

●Technical indicators such as material, wavelength range, dimensions (including shell dimensions), shell material, and weight are clear, facilitating selection and adaptation

●Spectrometer reflectance calibration

●Color detection and matching, image calibration

●Coating and color reflectivity measurement

●Aerospace remote sensing, ground mapping

●Chromatometer and spectrophotometer calibration
