Harmonic Beamsplitter OMB05-R355-T532&1064
Harmonic beamsplitters, sometimes called harmonic separators or dichroic filters, are designed to separate Nd:YAG laser harmonics at 45° incidence. They provide high reflection (99.5%) and transmission (95%) at specified wavelengths. The front surface has a beamsplitting coating designed for the reflected beam, while the rear surface has a V-type antireflection coating for the corresponding transmitted wavelength, reducing interference between front- and rear-surface reflections and minimizing reflection losses. JCOPTIX currently offers three wavelength configurations for different applications: 1064 nm reflection and 532 nm transmission; 532 nm reflection and 1064 nm transmission; 355 nm reflection and 532 and 1064 nm transmission. Contact technical support for other wavelength configurations.
