Waveplates APSAW-7 type can have a width of spectral range wider than 750 nm.  The graphs show the retardation dependences on the wavelength for plates that were manufactured using the new technology

Our new product. APSAW-5-Precise. The new technology allows varying a form of retardation curve as well as moving it along an y-axis. As a result, we can by order, either the bandwidth expands or accuracy enhances. We can improve the accuracy by special order to a phase shift of 90 degrees +/- Lambda/300.

We have developed a new technology for new types of superchromatic waveplates APSAW-5-Wide can have a width of spectralrange greater than 500 nm.

The design of multicomponent zero-order wave plates is described in Ref. 1. References 2 and 3 present the calculated and experimentally measured spectral dependences of the phase shift for three-component (achromatic) and five- component (superachromatic) wave plates. The spectral achromatization region can be broadened by increasing the number of components in the plate.4 The goal of this paper was to fabricate a seven-component zero- order quarter-wave plate and to measure...

Polymethyl methacrylate (PMMA) is a versatile polymeric material that is well suited for fabrication of many commercial optical components: lenses, fibers, windows, phase waveplates and others. Our focus is achromatic zero-order waveplates made of anisotropic PMMA which can be used to modify the state of polarization of electromagnetic radiation. Such waveplates have a broad range of application in devices where polarized laser radiation is used. For example, when tunable lasers...
