Wave plate about 15mm dia. x 1/2mm thick. In brass mount with retaining ring. Tested to work pretty good with a 445nm diode laser as seen in pics. Beam shot through Polarized beam splitter for vis. Rotate slightly and you get a pretty good variation maybe 25-75 or 20-80. Probably designed for a he-cad laser @ 442nm. May also work for a doubled ND:YVO4 @ 457nm Money back if not satisfied. I have two units available .Thanks for looking
