Large Zero Order Waveplates

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. Tower Optical large waveplates are made from Laser quality Crystal Quartz. Each plate is AR coated on both sides. Retardations are ½ or ¼ wave. The waveplates are offered either unmounted or mounted anodized Aluminum mounting rings.Click To Order 38.1mmClick To Order 50.8mmDidn’t See What You Need Please Click Here
