Spectroscopic retardation measurement PDMS-SP
Birefringence measure Fivelab

-  Application  -
≫Retardation / Ellipticity / Azimuth of Wave plate
≫Retardation of internal reflection / transmission for PBS / Prism
≫Retardation of pick-up mirror for CD / DVD
≫Birefringence of optical parts

-  Features  -
≫Since "Rotating retarder method" is used for this system, the system can perform
   very accurate measurement for all range of Delta value without retarder in/out.
≫Since detector unit can be turned independently from detector arm, it can detect
   parallel shifted light.
≫Standard software is including "Data Viewer" which make it easy to confirm about
   Retardation, Ellipticity, Azimuth.
