This memo describes the design of Z-cut crystal quartz vacuum windows with plastic antireflection layers for ALMA Bands 3 through 10. The windows can be made using readily available materials and proven construction techniques. Model calculations for each of the bands are presented showing the expected reflection loss and total insertion loss.
