Blue light exists in a large number of artificial light sources, such as LED screen, LED lamp, fluorescent lamp and so on. For example, mobile phones, computer monitors, fluorescent lamps, LCD screens, LED and other light

OHSP350B retina hazard rapid test instrument is an intelligent instrument which is specially designed for fast detection of blue light. It is an instrument that detects the effect of blue light. It has 4 functions: detection, measurement, screening and contrast. Detection: fast detection of anti Blu ray effect; measurement: LCD real-time display of measurement; screening: discriminating different anti blue light function; contrast: distinguish different blue light grades. In addition, the instrument is simple to use, a switch button can be used hand-held, and it is also very convenient to carry.

It mainly detects, measures, discriminating and contrasting all kinds of commodities that are harmful to artificial light source and various blocking blue light sources, such as blue light glasses and so on.

Measurable parameters:

1.CCT  Tc (K) and blackbody deviating  Duv

2. light illumination E (LX), candlelight E (Fc) spectral irradiance Ee (W/m2)

3. chromaticity coordinates (x, y), (U, V), (U ', V')

4. relative spectral power distribution P (lambda)

5. color index Ra, Ri (i=1 ~ 15)

6. color tolerance (SDCM, CIE and Macadam rectangle u 'V' round)

7. Dominant wavelengths, peak wavelengths8. light and dark visual ratio S/P

9. color purity, red ratio, green ratio, blue ratio, CIE1931 three basic color stimulus value X, Y, Z

10. blue light hazard weighted irradiance (mW/m2), safe allowed exposure time (S), hazard level

11. more functional parameters can be customized
