Laser Crystals and Components
Waveplates or retarders are used to alters the polarization state of the transmitting light. Most common used wavepates are half-wave plates and quarter-wave plates, while half-wave plates can rotate the plane of linearly polarized light, quarter-wave plates can convert linearly polarized light into circularly polarized light.
Hangzhou Shalom EO offers a variety of waveplates and retarders, including: true zero-order, zero-order, low-order and achromatic waveplates, these waveplates are made from quartz and MgF2 crystals, with cement, air space or optical contact design. Both off-the-shelf and customized modules are available. Zero-order wave plates has a wider temperature, incident angle and wavelength range than multi-order wave plates, and achromatic wave plates offers a constant phase shift independent of the used wavelength.
