Di01-R488/561-25×36

Theoretical Spectrum for Part Number: Di01-R488/561-25×36

488/561 nm BrightLine 双边缘激光二向色镜，25.2 mm x 35.6 mm，厚度 1.1 mm

针对荧光成像中最常用的激光器优化的二向色镜分束器，包括用于传统激光共聚焦显微镜（如共聚焦成像）的新型全固态激光器。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，可极大地减少相干激光引起的成像伪影。这种二向色镜分束器经过优化，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。

如果您对改进的平面度Flatness/反射波前差RWE版本感兴趣，您也可以考虑Semrock的超分辨率/TIRF二向色镜：
1mm厚度 Di03-R488/561-t1上的反射波前差RWE为1λP-V，针对反射直径达10mm的激光光束进行了优化，同时极大地减少了反射波前差RWE；
3mm厚度 Di03-R488/561-t3上的反射波前差RWE为λ/5 P-V，针对反射直径高达22.5 mm的激光束进行了优化，同时极大地减少了反射波前差RWE。
