Using an Integrating Sphere and LED Test Equipment for Measurement Accuracy

Integrating sphere is an optical measuring instrument, which can quantify the parameters of light source such as luminous flux, color temperature, light efficiency, etc. The integrating sphere is essentially a sphere of cavity wall coated with diffuse reflection material, with a sampling port. When the light source is irradiated, after multiple reflections, the illuminance on the inner wall can be homogenized, and various light sources (LED, laser, etc.) can be tested and uniform light sources can be detected and calibrated at this time.

Standard Integrating Sphere
Standard Integrating Sphere greatly improves the application efficiency of the optical field. Users can choose the suitable size of integrating sphere and aperture size according to the optical accuracy requirements to ensure that the instrument can get accurate spectral data. In addition, a variety of optical accessories can be configured according to actual needs, such as light sources, PD detectors, filter plates, aperture reducers, fiber interfaces, collimators and other components, to meet various optical applications such as spectral radiation calibration, light flux calibration, transmission reflection, etc. Integrating sphere technology can greatly improve the application efficiency, which is helpful for flexibly satisfying users’ requirements and bringing more convenience to the optical industry.
