  Luminaire Integrating Sphere Integrating sphere is one of the most important device for spectral and luminous flux measurement of light source. A deciding factor in choosing the appropriate integrating sphere is the maximum dimension of the light source to be measured. Larger sources require the use of larger integrating spheres in order to keep measurement errors to a minimum.

  LED Integrating Sphere Integrating spheres are widely applied in the photometric and colorimetric test system in led measurement applications. The inside surface of an integrating sphere is coated with a diffusely reflecting material which guarantees complete integration and homogenization of the emitted radiation.

  PTFE Integrating Sphere The Integrating sphere is an important instrument of optical measurement for enabling high sensitivity measurements. The sphere is made of a sintered PTFE, which is >98% reflective in the visible. Each of the integrating spheres can couple to our spectrometers to measure the total integrated reflectance of surfaces placed against the sphere's sample port.
