專業Phase Retarding Mirrors廠商

Used to convert beams with linear polarization into circular polarization, ULO Optic's phase retarders are mainly used in metal cutting systems to ensure consistent cut quality in all cutting directions.

ULO Optics manufactures both silicon and copper phase retarders. Silicon phase retarders are available in both λ/8 and λ/4 types (45° and 90° retardation). Copper phase retarders are available as λ/4 type only. They have a higher laser damage threshold than silicon phaser retarders.

   ● 90 degree +/- 3degrees (< 1 degree possible on request) phase retardation
   ● Typical reflectance > 98.5%
   ● Substrates up to 5“ diameter available
   ● available mounted in our mirror blocks
