How do you choose integrating sphere if you test small size but high power HID lamp?

HID lamp is high intensity discharge lamp. High pressure sodium lamp, high pressure mercury lamp, xenon lamp, metal halide lamp are all belong to HID lamp. We generally use Integrating Sphere Spectroradiometer Test System to test the photometric, colorimetric and electrometric parameters. Generally we suggest the diameter size of Integrating Sphere according to the size of lamp under test. If yo...

What is the Integrating Sphere?

Integrating sphere is a hollow sphere with high reflectance surface, it is widely applied in testing lumen, chromaticity coordinates, CCT, dominant wavelength and peak wavelength etc for light source or luminaries. The inner coating reflectance of integrating sphere is an important index for integrating sphere. The coating is ideal diffuse reflection material, the diffuse reflectance factor of the...
