Dual Wavelength Waveplates
Dual Wavelength Waveplates
shared：
The dual wavelength are made of high quality crystaline quartz and are available at quarter-wave and half-wave retardance. The waveplates are THG-PR polarization rotators and used to manage the polarizations of laser beams to obtain maximum conversion efficiency of third harmonic generations, such as 1064nm+532nm-->355nm. Two models are available: λ@1064nm&λ/2@532nm, λ@532nm&λ/2@1064nm.
