Liquid Crystal Variable Phase Retarder
from Arcoptix S.A

The liquid crystal variable phase retarder (or phase shifter) is a transmissive element with an electrically tunable optical phase retardance. Optical retardation is often obtained with piezoelectric mirrors. However this option is not ideal if robust and compact design is necessary. This product... [See More]
