Dual-wavelength waveplate

The double wavelengths waveplate is designed to give out a different retardance of two wavelengths. The double wavelengths waveplate are widely used in frequency conversion laser systems. The standard products from Surestech are λ@1064&λ/2 @ 532nm and λ@355nm&λ/2 @ 532nm. Our double wavelengths waveplates are available upon requirement. We can do the right design.
