滤光片型号：FF471/539-Di01-25×36
FF471/539-Di01-25×36 双边缘标准落射荧光二向色镜透过率曲线，Semrock
471/539 nm BrightLine 双边缘标准落射荧光二向色镜，25.2 mm x 35.6 mm，厚度 1.1 mm
Semrock多边缘二向色镜具有从高反射率到高透过率的两个或多个转变。Semrock提供多种二向色镜分束器，具有陡峭的边缘和非常高的反射和透射率。这种标准落射荧光二向色镜分束器仅针对LED或类似光引擎等宽带光源进行了优化。
BrightLine二向色分束器，用于CFP/YFP成像通道，针对Lumencor CELESTA光引擎进行了优化，使用445 nm、518 nm波长。
