Light-resistant Integrating Sphere
The integrating sphere is used for total luminous flux measurement. It uniforms the light by spatially integrating the collected light of light source. The integrating sphere has highly reflective diffusing plates formed on the spheres internal surfaces. These plates repeatedly scatter light rays from the light source with in the sphere to all other points to deliver uniform brightness distribution so measuring a portion of that light gives the total luminous flux. These years, the usage of integrating sphere for total luminous flux evaluation of light source is increasing. The large size integrating sphere over 1.5M is required for measuring a high brightness light source and a long light source such as fluorescent light.

Integrating Spheres - Luminous Flux Measurement For LEDs And Lamps
Konica Minolta Sensing Americas, Inc
One of the most important tests in light measurement is the assessment of the total radiant power or luminous flux of light sources using integrating spheres. An integrating sphere’s inside surface is coated with a diffusely reflecting material which guarantees complete integration and homogenization of the emitted radiation. The integrated light is then measured at the detector port.

Monochromatic, Fiber-Coupled LED Light Sources
LED light sources in the LS-MC1 series provide a constantly growing selection – currently amounting to over 20 – of narrow band single wavelength LEDs with a bandwidth of 15-50 nm FWHM, allowing precise work in a defined wavelength range. As a result of optimized optical coupling into the optical fiber – as with all of our light sources – with our LS-MC1 series we have achieved the highest possible luminance. The advantage of directly emitting monochromatic LEDs is their very high level of efficiency, because the entire radiated output is in the useful wavelength range.
