เครื่องวัดแสง รุ่น CLM-200H
Portable Chroma Meter
Product Description:
The CLM-200H Portable chroma meter is the successor to the CLM-200E. It can measure the color temperature, illuminance, chromaticity, excitation purity, luminous flux, RGB and dominant wavelength of various light sources. The CLM-200H meter exclusively does this under LED, Organic LED (OLED), and other forms of Organic Electroluminescence (EL).
When determining the accuracy of an LE illumination, color temperature measurements are particularly important. This instrument utilizes sensors that closely parallel the color-matching functions specified by the International Commission on Illumination (CIE). Depending on the application for which the CLM-200H is being used, results can be displayed through different color notations.
Some particularly suitable applications for the CLM-200H include but are not limited to, evaluating light distribution of LED illumination modules or fixtures, lighting production and adjustment, LED billboard development and maintenance, color-viewing cabinet maintenance, measuring projector light sources, and utilizing the instrument as a photographic color meter.
The CLM-200H was designed to be a highly effective tool for measuring the color temperature of white LEDs, a task that has been very difficult in the past. The CLM-200H is able to do this due to its ability to measure the chromaticity from the phosphor and also inspect light quality output of the final assembled white LED.
If you need to install the instrument in an inspection system, or use it in not-so-easily accessible darkrooms, the receptor head can detach from the main body
