The CL-500A Illuminance Spectrophotometer’s compact and lightweight design makes it easy to carry or hold in your hand for portable measurements. It can be used for the evaluation of high-class, next-generation lamps such as LED and EL illumination. In addition, the spectral irradiance waveform and peak wavelength can also be checked directly on the unit.<\/p>\n
The CL-500A<\/a> is equipped with standard tripod sockets on both the top and bottom surface, so it can easily be mounted on a jig facing either downward or upwards. It also includes convenient, easy-to-use software. This software will read measurement data from the CL-500A<\/a> directly into Excel. This allows for further processing of data to be performed using the included pre-set templates with graphs or various Excel functions. In addition to quantifying the color variations, the software is also equipped with a function to enable easy binning. Another function of the software the ability to display the MacAdam ADCM levels and CIE charts.<\/p>\n The instrument also has an informative color-rendering index display (CRI). The color-rendering index expresses the comparison between the light source being tested and a standard illuminant. The maximum value is 100, with the value decreasing as the color-rendering difference increases. This indicates how far the appearance, under the test light source, is from the natural color under sunlight. Scotopic illuminance and the S\/P ratio of scotopic illuminance can be measured with the instrument alone and with the included software. Other measurement functions include continuous measurement mode, average of multiple measurements, delayed measurement and the display of data at a specific wavelength.<\/p>\n
