Femtoline Laser Harmonic Separators with High Transmission SKU: 042-2530PHT
Harmonic separators with high transmission are dichroic beamsplitters that reflect one wavelength and transmit the other. The main advantage of a harmonic separator with high transmission is transmitted wavelength - T>98%@515 nm + T>99%@1030 nm, also the rear surface of harmonic…
