Waveplates

Tower Optical Corp.

Tower’s Zero order waveplates provide users with a high performance Crystal Quartz retarder with a clear aperture of 90%. These waveplates are air spaced, having a stainless steel spacer between two crystal quartz plates that form the zero order capability. Zero order waveplates are far less sensitive to temperature variations than multi-order waveplates. Air spaced waveplates have higher thermal stability and power handling capability than contacted or cemented waveplates. There are no failures as occur with contacted waveplates coming apart. Angular alignment of the waveplates is also more accurate.
