Femtoline Zero Order Dual Wavelength Wave Plates

EKSMA OPTICS offers zero order dual wavelength plates for Ti:Sapphire and Yb:KGW/KYW lasers.  When optical axis is turned by 45 degrees to input polarization, zero order dual wavelength waveplate rotates the fundamental wavelength  by 90 degrees and the polarization of second harmonic wavelength remains the same.
