![]() ![]() ![]() ![]() We also offer OEM and custom polymer wave plates upon request. These polymer wave plates can be mounted in Thorlabs' rotation mounts, as shown in the image above and to the right. Additionally, due to a well established production process using spin coating, our polymer wave plates have excellent retardance uniformity across the large clear aperture with low optical losses and low wavefront distortion of <λ/4 at 633 nm. A polymer wave plate can be used at an AOI up to 20° with only a 5% retardance decrease, compared to less than 2° for standard quartz wave plates (see graphs below). This design is advantageous for applications that require low sensitivity to AOI. LCP wave plates are designed to be true zero-order wave plates, which can provide stable retardance over a large range of angles of incidence (AOI). The mounted wave plates are epoxied into the housing attempting to remove the wave plate from the housing may result in damage to the wave plate. The glass plates have a broadband AR coating for either the 350 - 700 nm range, the 650 - 1050 nm range, or the 1050 - 1700 nm range deposited on the glass-to-air interfaces. We also manufacture Ø1/2", Ø1", and Ø2" versions in an SM05-threaded (0.535"-40), SM1-threaded (1.035"-40), or SM2-threaded (2.035"-40) housing, respectively, which are engraved with the item number and the fast axis orientation. The unmounted Ø1" version has the fast axis marked on the edge of the glass for ease of alignment. Thorlabs' Polymer Half-Wave Plates are fabricated from a liquid crystal polymer (LCP), which is laminated between two N-BK7 glass windows.
