APPLICATION

Measurement of Luminous Intensity The Chameleon-IH100 adapter provides CIE-127-2007 measurements of luminous intensity and all spectral parameters (e.g. dominant wavelength). Precision engineering maintains the specified measurement distance of precisely 10 cm from a detector with an area of 1 cm².
Measurement of Luminous Flux for High Power LED The Chameleon-LH200 integrating sphere adapter is available for measuring luminous flux and radiant power. The LED test fixture is used to push the LED into the opening of the sphere in such a way that all the light radiation is launched into the integrating sphere. The interior of the integrating sphere has a highly reflective and diffusing white coating which is specially flat for this purpose. Auxiliary lamp as a standard accessory.
Measurement of Luminous Flux for Lighting The Chameleon series can be equipped with a 1000mm diameter integrating sphere which extends luminous flux measurements up to 32000 lm. The large, 140mm diameter, Input ports is ideal for many lighting applications, especially for LED lighting which needs measurements of color uniformity from LED to LED-the lamp head. Application High Power Flash Lighting LED Lighting, LED Bulb
