Achromatic retarder - 62.6mm long.double 1/2wave. The Fresnel Rhomb is unique among retarders in giving a fractional-wave retardation nearly independent of wavelength, the variation due to change of index with wavelength being less than ±1% through the visible (450-700nm) and within... [See More]

from Thorlabs, Inc.
Thorlabs' Zero-Order Achromatic Wave Plates are built by aligning the fast axis of a Multi-Order Crystalline Quartz Wave Plate with the slow axis of a Magnesium Fluoride Wave Plate, where the optical path length difference between the two wave plates is either /4 or /2. The use of crystalline quartz... [See More]

from Tower Optical Corporation
Tower's achromatic waveplate (AWP) is similar to a zero-order waveplate, which is made from two pieces of crystal quartz except that the AWP is composed of one piece of crystal quartz and one piece of magnesium fluoride, MgF2. Both of these materials are birefringent, however, by proper matching of... [See More]
