The CL-200A chroma meter is the successor to the CL-200. It can measure the color temperature, illuminance, chromaticity, excitation purity, and dominant wavelength of various light sources. The CL-200A meter exclusively does this under LED, Organic LED (OLED), and other forms of Organic Electroluminescence (EL).

When determining the accuracy of an LEDs 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 CL-200A is being used, results can be displayed through different color notations.

The CL-200A 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 CL-200A 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.

The CL-200A runs on batteries and is extremely lightweight. This tool was ergonomically designed in this way so that it can fit into the palm of your hand. The low battery indicator alerts you as to when you need to either change or recharge your batteries. Also, the included CL-S10w data management software allows users to transfer data to Excel with ease. Conversely, the instrument can be linked directly to a PC and controlled using a computer. In order to quantify color variations, Japanese Industrial Standard (JIS) calculation ranking functions are included with the software.

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. It is then possible to collect data by connecting the receptor head to the body by utilizing a LAN cable. Up to 30 receptor heads can work to collect multi-point measurements. A user-friendly calibration function makes it easy to compare measured and sample measurements.

Some particularly suitable applications for the CL-200A 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.

小巧,方便攜帶 CL-200A的機身非常小巧輕便,可以貼合你的雙手。儀器可用電池供電,方便您隨身攜帶並且可以在現場使用。
儀器的測量探頭可從主機身上拆卸下來,並通過一根連接線*與主機進行相連,這樣可使測量探頭單獨進入積分球、暗室、檢測系統等裝置。 *配件需另外選購
當CL-200A結合數據管理軟件CL-S10w(標準配件)一起使用時,可通過機身上的按鍵進行測量並將數據傳輸到Excel ®表格中。
用於照明產品的測量及調校 在一些公共場合,會使用到各種類型的照明光源,有時有必要對光源的顏色進行測量評估。 比如,在一些餐廳,通過使用CL-200A調整照明光源的顏色,可使食物看起來更美味可口一些 用於評估光源的特性 可對LED照明模組、組合光源等一些產品的光線分佈進行測量評估。 用於標準光源箱的維護 在一些工業領域,如印刷,塗料等行業,會經常使用如右圖所示的標準光源箱來控制觀察條件並對產品的顏色進行視覺評估。標準光源箱中通常都是使用特定的熒光燈、鹵素燈等來提供幾種特定色溫和照度的照明光線。CL-200A可對這些照明光源進行日常的檢測,以及時了解是否需要更換燈管了。 用於投影儀的光源研究和色彩檢測 CL-200A可對一些小型投影儀的白平衡和均勻度進行測量評估。CL-200A可擴展多探頭的功能,不僅只測量投影屏幕的中心點,還同時可以對幾乎整個投影區域進行測量評估。 用於戶外LED屏幕的研發和維護 CL-200A可對LED模組的照明質量進行控制。比如模組中混合使用了其他顏色、色調的二極管,整體屏幕看上去就會有雜色和斑點。通過使用CL-200A進行模組的色溫和色調,並基於測量數據進行調整和選擇,即可使整個屏幕的色彩一致性得到提高。
