LMK 7-128成像亮度計應用

高解析度顯示器測量與DeMura校正 －OLED、µLED、Micro-LED、LCD面板像素級測量：均勻性、局部對比、次像素分析。結合內建µShaking和DeMura軟體，建議使用這款測量頭進行線上DeMura校正。完整內容： DeMura與像素級測量。
照明和號誌檢查（分箱模式） — 一般照明燈具、號誌燈、交通及鐵路號誌、背投影螢幕；一台攝影機即可覆蓋顯示器和照明模式。
頭燈、日間行車燈和外部汽車照明計量 ——像素級矩陣式、高清和ADB頭燈；結合TechnoTeam的螢幕測角光度計，以比傳統掃描測角光度計快得多的速度對頭燈、日間行車燈和一般照明進行間接光強度分佈（LID）測量快得多。
