Integrating sphere as an instrument for sphere integration

If your application requires measurement of a widely diverging beam, an integrating sphere is the best option to consider. An integrating sphere is an optical component that captures a light beam and enables you to measure the power in the beam under conditions that would otherwise be very challenging. A widely diverging beam that might overfill a regular sensor aperture. Sphere integration LPCE-2...

What is the function of the optical integrating sphere

The functions of the optical integrating sphere tester include light receiving, uniformly illuminated object surface, spherical parallel light tube, etc. Its principle is that after light is incident from the input hole, the light is uniformly reflected and diffused inside the sphere. Below take Lisun’s optical integrating sphere system as an example to introduce it in detail. The role of op...

Integrating-sphere system for measuring the optical properties

The integrating sphere is a cavity sphere coated with a white diffuse reflection material on the inner wall, also known as a photometric sphere, a luminous sphere, etc. One or several window holes are opened on the spherical wall, which are used as light inlet holes and receiving holes for placing light receiving devices. The inner wall of the integrating sphere should be a good spherical surface,...

What does an integrating sphere measure

Generally speaking, the optical diffuser, when used carefully, can reduce the small errors caused by the uneven distribution of the incident light source on the detector or the deviation of the beam during measurement, so the accuracy of the integrating sphere measurements can be improved. However, in precise measurement, an integrating sphere must be used as an optical diffuser to minimize the ab...
