Luminous Color & Illuminance Detectors

The CT-4501 luminous color detector is designed with a precise x,y,z tristimulus spectral match to the CIE color function enabling accurate illuminance, x,y chromaticity values and color temperature measurement of broad band emitting light sources. The CT-4501 is compatible with the HCT-99D color meter and also the P-9801 8-channel radiometer/photometer/colorimeter.

The detector is supplied with a 2m long coaxial cable with selectable -1 or -4 type connector for use with Gigahertz-Optik's range of optometers. Internationally traceable calibration & certification of illuminance in lux and color within the specified spectral sensitivity range is provided.
