Tower’s Large aperture Zero order waveplates provide users with the capability of handling new applications where beam size and/or beam position moves over larger distances. The waveplates described here 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.
