Frequently Asked Questions

An Achromatic Waveplate is made from two different substrate materials such as crystal quartz and magnesium fluoride. It is not sensitive to the wavelength change.

The working wavelength of a single material waveplate is very limited because of the dispersion of the material.

The damage threshold of a High Power Waveplate is >10MW/cm2.

A Dual Wavelength Waveplate is particularly useful when used in conjunction with other polarization sensitive components to separate coaxial laser beams of different wavelength. It is widely used to improve conversion efficiency in solid double frequency laser device.

The thickness tolerance of Photonchina's waveplates is a only small fraction of a micron.
