 詳細介紹

LE7是Image Engineering(德國愛莎ESSER)新推出的標準光源燈箱,采用LED照明,內置光譜計,可以產生光譜非常接近自然光的光源,模擬1900K--18000K任意色溫。
LE7根據內置的LED數量,主要有3個型號:LE7-2,LE7-4和LE7-IR.
LE7-2,亮度25 lx——2000 lx;LE7-4,亮度25 lx——4000 lx.LE7-IR,亮度25 lx——4000 lx,光譜范圍:350-1050nm
如需低照度測試,可加入減光板,亮度可<1 lx;
如需提高均勻度,可加入均光板,均勻度>99%.
如需模擬特定環境光,可用光譜采集器采集后,導入LE7完美模擬還原!
