We can supply you a series of waveplates such as: Low Order Waveplate; Zero Order Waveplate; Dual Wavelength Waveplate; Achromatic Waveplate.

Core Optronics low Order Waveplates are much better than the multi-order waveplates because of its thinner thickness(less than 0.5mm), better teermperature(38 ), wave length(1.5nm) and incidence angle(4.5 ) bandwidth and high damage threshold.  These properties make it widely used in common applications.

Core Optronics zero order waveplate is a quarter or half-wave retarder made from two plates of quartz within their fast axes crossed. The difference in thickness between the two plates determines the retardance. Zero-order retarders provide accurate retardance over a broad range of wavelengths and are more durable than single element retarders. Zero order waveplate shows better performance than multiple order waveplates, it has broad bandwidth and a lower sensitivity to temperature and wavelength changes. It should be considered for more critical application.

Core Optronics dual wavelength waveplate is a multiple waveplate that provide a specific retardance at two different wavelengths. It is particularly useful when used

Core Optronics achromatic waveplate is similar to Zero-order waveplate except that the two plates are made from different materials, such as crystal quartz and magnesium fluoride.
