Zero-order wave plates

BFi Optilas has announced that it now stocks 1-inch and 100mm diameter zero-order wave plates for 1064nm. These retardation plates can be supplied as-is, core-drilled, or diced to almost any dimension in just a day or two, and they are already coated with the company's high energy, low loss IBS anti-reflection coatings (R < 0.1 per cent). The company also offers custom multiple order and zero order crystal quartz and sapphire wave plates in sizes from 1mm to more than 2-inch for research, semiconductor, biomedical and aerospace applications.
