Integrating Sphere

An integrating sphere is basically a hollow spherical cavity covered with a diffuse, highly reflective white coating. It is mainly used to diffuse the radiation in all directions by scattering and reflecting the emitted light multiple times.

Spectroradiometers are generally coupled to integrating spheres to measure the characteristics and quantity of the light source being tested. Integrating spheres are available in a variety of sizes based on the construction, dimensions and power output of a light source.

How are you measuring?

With fibers and other accessories even more type of measurements are possible. Often used accessories are integrating spheres, cuvettes for fluids, light sources or filter holders.

A cosine corrector collects the light from the half space under 180 degrees. A typical application is the illuminance measurement of a lighting situation.

Consumers are used to enjoy top-quality displays in their mobile phones, tablets, laptops and even cars. Emerging technologies such as lighting surfaces for office and home illumination are expected to look equally perfect. Both displays and luminous surfaces are the main application areas for imaging colorimeters.

2D imaging

Measuring the luminance or color values at a specific location of the device under test is a typical use case when measuring displays. It can, however, also be meaningful to assess reflected light.
