Glued Zero Order λ/4 Waveplate (Retarder)

Glued Zero Order Waveplate is made of two mutiple order waveplates . The glued waveplate can improve the effect of temperature on te waveplate to some extent, but it increases the sensitivity of waveplate retardance to wavelength and incident angle. We provide glued zero order waveplates which are made of quartz crystals. Retardance includes λ/2 and λ/4.
