Spectrum, Transmittance and Reflectance Tester

The wavelength range of the LMS-6600TR is 350-950nm. It integrates the functions of spectrum, transmittance, saturation, reflectance, L, A, B, etc. It uses a 5-inch large screen to display measurement parameters and curves in real time. It is easy and quick to use and can directly test products such as materials and lenses.

Measurement:
Transmittance, Reflectance , Total Transmittance, Saturation (C*), Degree of Brightness (L*), Yellow-Blue Degree (a*),Red-Green Degree (b*), Absorbance, Tone (H*), illuminance (lux), E(Fc), Ee(W/m2), Tc (K), Duv Correlated Color Temperature (CCT), Chromaticity Coordinates, CRI, Purity, Cut-off wavelength, Peak Wavelength, Dominant Wavelength, Half Bandwidth, Center Wavelength, Centroid Wavelength, Total Color Difference, Brightness Difference, , CCT Difference, SDCM Diagram, Spectrum Diagram
