透射式多色温亮度可调灯箱(内置光谱计) LE7 with iQ-LED Image Engineering LE7 恰询 恰询
 详细介绍

LE7是Image Engineering(德国爱莎ESSER)新推出的标准光源灯箱,采用LED照明,内置光谱计,可以产生光谱非常接近自然光的光源,模拟1900K--18000K任意色温。
LE7根据内置的LED数量,主要有3个型号: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,光谱范围:350-1050nm
如需低照度测试,可加入减光板,亮度可<1 lx;
如需提高均匀度,可加入均光板,均匀度>99%.
如需模拟特定环境光,可用光谱采集器采集后,导入LE7完美模拟还原!
