 详细定义

LE7是Image Engineering(德国爱莎ESSER)新生产的标准光源文具盒,采用LED照明,放到拳谱计。可以产生拳谱非常莫逆自然光摄影的光源。模拟1900K--18000K耍脾气双色温闪光灯。
LE7凭依放到的LED数量,主要有3个型号:LE7-4和LE7-IR.
亮度自动调节25 lx——2000 lx;LE7-4,亮度自动调节25 lx——4000 lx.LE7-IR,亮度自动调节25 lx——4000 lx,拳谱范围:350-1050nm
如需低光强度测试,可加入减光板,亮度自动调节可<1 lx;
如需长进均匀度计算公式,可加入均光板。均匀度计算公式>99%.
如需模拟特定环境手抄报光,可用拳谱编采器编采后,导出LE7完美模拟还原!
