MK350N PREMIUM Spectroradiometer

The integrating sphere is a spherical device with a reflective inner coating, which allows the measurement of luminous flux and color performance when a light source is inserted.

It is a system for measuring: luminous flux (lm), radiant power (W), efficiency (lm/W), spectral power distribution P(λ), chromaticity coordinates, correlated color temperature (CCT), color rendering index (Ra), SDCM, dominant wavelength, as well as electrical parameters such as voltage, current, power, power factor, etc. The device is designed to measure luminaires, lamps, LED PCBs, LED modules, and more.

Everfine integrating spheres are specifically designed to perform the most precise spectral, colorimetric, and photometric (luminous flux) tests on any light source: luminaires, lamps, and LED sources.

Están fabricadas en acero laminado en frío y entre sus propiedades de revestimiento destacamos el recubrimiento de reflectancia difusa, que parece casi lambertiano (perfectamente difuso) y el Recubrimiento interno SpektronTM R98, una tecnología exclusiva. También dispone de propiedades no tóxicas, duraderas y ópticamente estables en el tiempo; además de estar equipadas con una plataforma elevadora en la parte inferior de la esfera.
