Tektronix J6503
Luminance Probe 0.1 to 199,900 Footlamberts
Description
This unit measures luminance in footlamberts where light scattered or emitted by a surface must be measured.
The probe is pointed at the emitting surface.
The unit's response is closely matched to the CIE photopic curve, ensuring accurate results even when measuring spectrally different light sources.
The accepted angle is approximately 8 degrees, which is determined by internal field stop apertures.
