Multiple Order & Dual Waveplates

Multiple Order Waveplates

Tower’s multiple order waveplates consist of a single plates of laser quality crystal quartz.

Because their retardation adds some integer number of waves to the desired fraction (λ /4, λ /2), they are many times more sensitive to temperature and wavelength than zero order waveplates. Therefore they perform well only in laboratory environments and in mono- chromatic light.

Tower Optical multiple order waveplates are AR coated on both sides. Standard retardations are λ /4 and λ /2; other values are available upon request.

They are offered either unmounted or mounted in an anodized aluminum ring.

Multiple order Waveplates can be diced or edged as small as 1mm in diameter or square.

Dual Wavelength Waveplates

Dual Wavelength Waveplates are designed to operate at two different wavelengths. They will also be coated at both wavelengths. Contact us for specify design capabilities.
