ommercial Retarders are our most affordable line of zero-order waveplates. They are suitable forapplications where transmitted wavefront quality is not as critical.These retarders use commercial quality glass windowsand are designed as a low-cost alternative to our Precision Retarders described on pages 28-29. Basic construction is the same as described on page 23.Both quarter- and half-wave retarders are available forcommon wavelengths in the visible to near infrared region. All Meadowlark Optics’ retarders have their fast axis conveniently marked.Custom retardance values are available from 400-1800nm. Please call to discuss your application and to request a quote.
