High-Precision Portable CS-LM01 Spectral Illuminance Meter (ColorSpace) | Optical Measurement Device - Suitable for Image Detection and Laboratory Testing of Light Source Environment Illuminance

The CS-LM01 Spectral Illuminance Meter utilizes a high-speed AMR processor and electronic CCD optical sensor, designed based on the long-focus cross-asymmetric CT spectroscopic system principle. It features a compact size, stable performance, high precision, and portability. The device is equipped with a 5.0-inch high-definition capacitive touch display, offering a user experience similar to operating a smartphone, making it easy to use.

Users can perform light source parameter sampling and measurement anytime and anywhere, and with the ColorSpace Light Control software, they can analyze and process the test data. The device provides excellent measurement linearity and accuracy, and can also be used for calibration and closed-loop adjustment of light source products during use.

Measurement parameters：
    1. Correlated color temperature Tc (K), black body deviation from Duv.
    2. Illuminance E (lx), candlelight E (Fc) radiant illuminance Ee (W/m2).
    3. Chromaticity coordinates (x, y), (u, v), (u', v').
    4. Relative spectral power distribution P(λ).
    5. Color rendering index Ra, Ri (i=1～15).
    6. Color tolerance SDCM (McAdam ellipse, rectangular box and CIE u’v’ circle).
    7. Dominant wavelength, peak wavelength, center wavelength, centroid wavelength, half-width.
    8. S/P ratio of light to dark vision.
    9. Color purity, red ratio, green ratio, blue ratio, CIE1931 three primary color stimulus values X, Y, Z.
