Quartz waveplate GCL-0606 series

Multi-order waveplates are made of high quality quartz crystals, providing delays of half and quarter wavelengths at various commonly used wavelengths. λ/2 waveplates are usually used to rotate the polarization of light, while λ/4 waveplates are used to convert linearly polarized light to circularly polarized light. Multi-order waveplates are more sensitive to wavelength and temperature changes than zero-order waveplates. Material：Crystalline Quartz Operating Wavelength：441.6nm-1550nm Retardance Accuracy：λ/4
