Wave retarders transform the polarization of light using birefringence and include both waveplates and polarization rotators. They are used in applications where optimization, control, or analysis of polarization is required. This includes rotating polarization, converting between linear and circular polarization, adjusting ellipticity, or separating wavelengths. We offer a line of high-performance, high damage threshold quartz retarders that includes zero-order, multiple-order, and dual-wavelength waveplates, as well as 90° polarization rotators, the choice being governed by operating wavelength, temperature range, environmental and laser damage durability, and or field of view. They are available in a wide range of sizes, wavelengths, and assembly configurations to fit your application. We can also provide semi-custom and custom retarders to your exact specifications.

Used to rotate polarization (λ/2 retardation) or convert between linear and circular polarization (λ/4 retardation). Recommended when sensitivity to wavelength and temperature is not critical • High performance specifications and laser damage threshold • Best suited to narrow bandwidth and operating temperature range.
Compound zero-order waveplates used to rotate polarization (λ/2 retardation) or convert between linear and circular polarization (λ/4 retardation). Recommended for use with diode, tunable and femtosecond lasers • High performance specifications and laser damage threshold •Wide useful bandwidth • Excellent thermal stability • Choice of optically contacted, contacted in a ring mount, and air spaced versions
Quartz rotators are used to easily rotate the linear polarization of a beam through 90°. Simply placed in the beam at normal incidence without requiring angular adjustment. • Alignment-insensitive high damage threshold rotator • Based on optical activity of crystal quartz • Single wavelength operation • Custom wavelengths, rotation angles, and sizes available
