The true zero-order wave plate can produce accurate phase delay. Compared with the ordinary zero order wave plate, the true zero order wave plate has better extinction ratio and better delay accuracy. Compared with glued true zero level, single true zero level is only a piece of quartz, which is mainly used in 1310 and 1550 communication bands.
