Laser quality crystal quartz Clear apertures of 8, 10, 15, 23, 34 & 46 mm Mounted or unmounted Retardations of ¼ and ½ Waveplates are AR coated High performance specifications

Multiple Order Waveplates

Tower’s multiple order waveplates comprise a single piece of laser quality crystal quartz.

Because their retardation is the desired fraction (/4, /2) plus some integer number of waves, 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 /4 and /2; other values are available upon request.

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