產品介紹

INTRODUCTION >> TechnoOptis (TOPCON) BM-7AC
Introduction of TechnoOptis (TOPCON) BM-7AC

TechnoOptis (TOPCON) BM-7AC色彩輝度計是BM-7系列最新一代的色彩輝度計機型,為取代最暢銷的BM-7A色彩輝度計所設計之替代機種,此款色彩輝度計(Luminance Colorimeter)在TechnoOptis (TOPCON)光學特性量測產品中,以其卓越的性價比著稱,它不僅產品價格實惠,還具備色度精度高、量測準確度高、測量速度快等優點,因此成為平面顯示器(FPD, Flat Panel Display)和光源燈製造領域的標準機型,用於輝度(Luminance)和色度(Chromaticity)測量。

廣泛被平面顯示器(FPD, Flat Panel Display)及光源燈具相關製造領域做為輝度(Luminance)、色度(Chromaticity)測量的標準機型,BM-7AC色彩輝度計適用於光源亮度與色度測定,適合於產線內測量和光源輸出調整等多種應用場景及用途。

此外,BM-7AC色彩輝度計具備色彩校正功能(Color Correction Function),能夠與TechnoOptis (TOPCON)生產的SR系列分光式輻射度計(Spectroradiometer)之基準儀器或同類機型直接連接進行色彩補正,這有效降低了機差問題,確保長期提供穩定的量測品質。

產品特色

FEATURES >> TechnoOptis (TOPCON) BM-7AC
  • 色度精度大幅提升 (與BM-7A色精度比較圖)
    比擬人眼的比視感度曲線(Spectral Luminous Efficiency Curve)實現與CIE 1391色彩匹配函數(Color Matching Function)相同等級的光譜靈敏度特性(Spectral Sensitivity Characteristic)來提高色度精度。 Chromaticity-Accuracy
  • 可高速測定輝度
    0.5秒高速測定輝度,適合生產線上量產測試需求與機構整合量測需求。
  • 輝度精度
    輝度測定精度±2%以內(測定角度2°,輝度5 cd/m2以上,採用自動範圍模式測定標準A光源)
  • 自動範圍模式測定
    自動模式功能可依照待測物樣品的明亮程度,自動選擇適合的測定範圍
  • 模擬輸出(選配型號:BM-7AC ANA)
    相對應X、Y、Z的三通道模擬輸出(Analog Output)可以連接計數器、示波器(Oscilloscope)進行記錄和波形觀測、更可發揮其線上測定功能。
  • 搭載USB介面
    標準介面搭載USB2.0與RS-232C,搭配CS-900A軟體可與輝度計連線進行自動量測。
  • 高耐久性
    採用非旋轉輪盤方式的濾片切換機構,擁有更好的耐久性。
