Measuring object Type: LED, Osram, OSTAR, 4-Chip, with lens

Measurement with color filters Two measurements with the color glasses BG25 (blue) and OG530 (yellow) have been done. The ray data of the two measurements are related to the measured luminous flux measured by the V(λ) adapted photometer. For this a factor between the integral of the ray data measured by the camera and the luminous flux measured by the photometer has been calculated.

BG 25 - blue OG 530 – yellow

Integral of camera data 0.362405 37.1943

Luminous flux of photometer 59.223 59.221

Position and orientation The following views are showing the origin position of the ray data coordinate system referring to the measuring object. The images are captured by the luminance measuring camera at the given angles of the goniometer coordinate system (spherical coordinates).
