Light performance test

Optical performance is a big index, which is composed of solar transmittance, solar reflectance, solar absorption rate, visible light transmittance, visible light reflectance, total solar blocking rate, ultraviolet blocking rate, shading coefficient, U-value and other small indicators. When light hits paper, plastic, glass, metal and other materials, it shows normal reflection, but the number of reflections is different. Manufacturers of lighting products must ensure that they meet all the performance requirements of their target markets worldwide.

Introduction to Light Performance Test

Light performance test

Performance testing can be in accordance with ISO, ASTM, DIN, GB, HB and other standards to complete the light transmittance of various products, tinting strength, hiding power, gloss and other optical performance testing.

The optical performance test is to test the luminous power of the laser at a certain temperature, characterized by comprising: a heating device for heating the laser to a required temperature, the heating device can place at least two lasers at the same time: a driving power supply, which is electrically connected to the laser, and is used to provide a driving voltage to the laser; an ammeter, which is electrically connected to the laser, for monitoring the current through the laser; an optical power meter, the optical fiber is connected to the laser for monitoring the optical power of the laser.

Light performance test main content:

1. Refractive index

2. Dispersion and dispersion coefficient

3. Birefringence and extraordinary refractive index

4. Reflection and reflection coefficient

5. Total reflection

6. Absorption coefficient

7. Scattering
