Integral sphere is generally used as an ideal diffuse light source or homogenizer to eliminate the unevenness or polarization direction of the emitted beam caused by the characteristics of the light source itself. The reason why the integrating sphere has this characteristic is mainly due to multiple diffuse reflections of incident light inside the integrating sphere.

The inner surface of the integrating sphere is a complete geometric sphere with equal radii everywhere. The inner wall of the sphere is a uniform diffuse reflection surface, which has the same diffuse reflection ratio for various wavelengths of incident light. There is no object inside the sphere, and the light source is only regarded as an abstract light source that emits light without a physical object. Its basic composition is as follows:

The entire spherical shell is empty inside, with a white diffuse reflection layer painted on the inner wall;

The diameter of the ball is determined by the size of the sample to be tested and the lamp to be tested;

Three small windows are opened on the ball wall, namely the incident window, sample window, and sensor window.

Integral sphere is a non-standard product that can be customized according to customer requirements for any structure and size of the product

There are usually several types of scoring balls:

Universal Integral Sphere

The structural design of the universal integrating sphere is very flexible, and users can choose the size, opening direction, and reflective material of the integrating sphere. By changing the accessories of the integrating sphere, such as light sources, accessories, and opening reducers, different applications can be achieved

Optical measurement integrating sphere

The luminous flux test integrating sphere is used to measure the total luminous flux output of the light source, supporting 2 π and 4 π tests of the light source.

Uniform light source integrating sphere

Composed of an integrating sphere, power supply, light source, and controller, it can achieve uniform Lambertian diffuse scattering light source output.

Infrared gold-plated integrating sphere

The gold-plated series integrating sphere is designed for high-power measurement, with a spectral range from near-infrared to mid infrared (NIR-MIR)
