理想的二向色镜，适用于荧光成像中最常用的激光器，包括较新的全固态激光器。该类别中的所有分束器在激光波长下都具有出色的反射率，并且具有抗反射（AR）镀膜，可极大限度地减少相干激光引起的成像伪影。这种激光二向色镜经过优化，可以反射直径高达2.5毫米的激光光束，同时最大限度地减少反射波前差RWE。
对改进的平面度Flatness/反射波前差RWE版本感兴趣吗？您也可以考虑Semrock的超分辨率/TIRF二向色镜：
1mm Di03-R561-t1上的1λP-V RWE，针对反射直径达10mm的激光光束进行了优化，同时将RWE降至极低；
3mm Di03-R561-t3上的λ/5 P-V RWE，针对反射直径高达22.5mm的激光光束进行了优化，同时极大限度地减少了RWE。
