VL-3701 - Data Sheet

Illuminance is the most frequently made measurement within general and specialist lighting applications.  The two most important qualities required of a high precision illuminance detector are a spectral responsivity that is very well matched to the ideal V(λ) photopic curve and a spatial response that provides cosine correction. The VL-3701 meets the high standards of DIN Class A classification for both these parameters. Photometric detectors offer a convenient solution for measuring illuminance (lux) simply, quickly and over a very wide dynamic range. When suitably calibrated, additional photometric quantities including luminance (cd/m2), luminous flux (lumens), and luminous intensity (cd) can be measured in conjunction with accessories such as lenses, integrating spheres and goniometers.
