General Optics
Waveplates
Convert linear into circular polarization with quarter-wave plates or rotate the polarization plane of a linearly polarized laser with half-wave plates.
These CdS waveplates offer precise retardation accuracy, excellent transmission, and high-power handling capability. They transmit visible light which simplifies system alignment. Both mounted and unmounted configurations are available.
Waveplate Capabilities
Coherent manufactures both multiple-order and zero-order waveplates. Zero-order waveplates are less sensitive to temperature and operating wavelength variations.
