Konica Minolta CL-500A Illuminance Spectrophotometer

Details

The CL-500A’s convenient measurement functions include continuous measurement mode, display of the averaging of multiple measurements, delayed-measurement function, and the display of data at a specific wavelength. The spectral irradiance can be measured at 1-nm pitch from 360nm to 780nm, so it can be used for measuring the color of light and photosynthetic photon flux density (PPFD). High speed measurement is possible using the Software Development kit (5 times/second).

The data management software CL-s10w, is included as a standard accessory. It includes a template for expressing the chromaticity variation of illumination light sources such as LEDs or OLEDs in terms of the MacAdam SDCM (Standard Deviation of Color Matching) step. This allows display of color differences that closely match visual judgment. The software is also equipped with an LED binning function and a spectral irradiance waveform display.

CL-500A 是柯尼卡美能達推出的首款輕便、手持式的分光輻射照度計。憑借先進的光學傳感技術和創新的設計，CL-500A可用於評估新一代光源如LED、OLED、有機EL照明的顯色指數、照度、色度、相關色溫等參數。

無論在實驗室研發還是照明現場測量，CL-500A 都可以滿足使用，為用戶提供便攜輕鬆的操作體驗。CL-500A運用了分光原理，內置光柵和傳感器陣列使其可以對光源光譜進行分析，通過光譜數據公式計算光源的顯色指數。顯色指數是對光源的光譜屬性和光品質定義的重要評估標準。用CL-500A可以測量得到一般顯色指數Ra和特殊顯色指數R1~R15。用傳感器陣列的另一個好處是可以復現光源的光譜圖，對如LED、OLED、高壓燈這類波峰能量集中、半波寬較窄的光源的光譜圖有很好呈現。

CL-500A不但可以測量顯色指數，還可測量照度(lx)、色坐標(1931xy,1976u’v’)、相關色溫T∆uv、三刺激值XYZ、特徵波長λ、色純度Pe、色差值。通過隨機附送的軟件CL-S10w，可連接電腦顯示光源的顯色指數評估圖、色溫色坐標圖、光譜數據等。針對同一批次LED也會出現較大色差的問題，軟件提供按顏色對LED分級的功能。

可通過電腦軟件CL-S10w，連接最多10台CL-500A同時進行多點測量，方便用戶對環境的照度均勻性、光源色溫進行跟蹤評估。
