Light performance test
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
Common light performance test products are
Including semiconductor lighting (LED light sources and lamps), incandescent lamps, fluorescent lamps and discharge tubes, energy-saving lamps, HID lamps, street lamps, automotive lighting, traffic lights, sun equipment, office lighting, courtyard lighting, flat-panel TVs, etc.
