由于多光子系统采用能量非常高的脉冲激光，因此需要发射片在激光波段范围 ( 通常 680 - 1064 nm) 的截止深度达到 OD8+，另外也需要二向色镜在此波段范围具有高反射率，而在可见光区域具有高透过率。为了避免激光将检测器损坏，在多光子系统的检测光路中，建议首先永久放置一片 OD8+ 的短通滤光片，然后在检测器前根据具体的需求放置对应的带通滤光片 ( 在
激光波段有 OD6+ 的截止深度 )。
用于 GFP 双光子成像的滤光片配置 : ZT775sp-2p 为二向色镜，用来反射 2p 激光并透射荧光；ET750sp-2p8 为短通发射片，可在 2p 激光波段提供 OD8+ 的截止深度；ET525/50m-2p 为带通发射片，用来接收 GFP 荧光，同时在 2p 激光波段提供 OD6+ 的截止深度。
