Spectrum, Transmittance and Reflectance Measurement Device

The LMS-6600TR operates within a wavelength range of 350-950nm, integrating functions for spectrum, transmittance, saturation, reflectance, and chromaticity measurements (L, A, B). It features a 5-inch high-definition IPS capacitive touch screen, displaying measurement parameters and curves in real time for ease of use. The device is capable of directly testing materials and lenses, offering comprehensive measurements including 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. The device adheres to standards such as CIE 177 “Color Rendering of White LED Light Sources”, CIE-13.3 “Method of Measuring and Specifying Colour Rendering Properties of Light Sources”, Optical-Engineering-49-3-033602 “Color Quality Scale”, and IEEE “Recommended Practices for Modulating Current in High-Brightness LEDs for Mitigating Health Risks to Viewers”. Specifications include spectral resolution of ±0.2nm, reproducibility of ±0.5nm, chromaticity coordinate accuracy (Δx, Δy) of ±0.005, correlated color temperature CCT range of 1,000K to 100,000K (±0.6%), and illuminance range of 5 to 200,000lx. The device is powered by a 4000mAh rechargeable Li-ion battery, providing up to 20 hours of continuous operation. Dimensions are 135mm x 80mm x 23mm, and it connects to a PC via USB cable, with English version software compatible with Win7, Win8, Win10, Win11.
