Illuminance Spectrophotometer CL-500A

The CL-500A is Konica Minolta’s first compact, lightweight illuminance spectrophotometer which can be used for evaluation of light sources including next-generation lamps such as LED and EL illumination. The advanced sensor measures CRI (Colour Rendering Index), illuminance, chromaticity, and colour temperature of virtually any light source, the built-in display means that it is suitable for use in the lab or out in the field.

Main applications

Spectral evaluation of light sources including next-generation lamps such as LEDs, OLEDs and EL illumination
Checking the illuminance, chromaticity, dominant wavelength and correlated color temperature of various kinds of light sources including organic EL lighting (OLED), LEDs, etc.
LED billboard development, quality control, and maintenance
Evaluating the light distribution characteristics of LED illumination modules
Evaluating the illuminance distribution of lighting fixtures
Building and interior lighting research
Spatial lighting production and adjustment
Color-viewing cabinet maintenance
Projector light source research and color inspection
Checking environments for psychological research experiments
