Gigahertz Optik

Description :

The ISM-50-R-V01 integrating sphere light meter is used for measurement of light reflectance, the degree of the scattered reflectance and calculation of the regular reflectance proportion. Sample illumination is done from an 8° angle. The regular or scattered reflected light from the sample is captured by the integrated sphere. This 8/d geometry corresponds to the specifications in DIN 5036 section 3. the light source is set to a 2856 K color temperature (standard illuminant type A). The high-quality silicon photodiode of the photometric detector is carefully matched onto the V(λ) responsivity function through a multi-layer spectral correction filter. Integrating spheres with a large diameter such as the ISM-50-R offer a wide detection angle for scattered reflected light.
