Super broadband circularly polarizing plate is realized by combining SB-RETAX-1/4λ with a broadband polarizer because constant linear 1/4λ retardation is realized for any wavelength ranging from 450nm to 1100nm with this waveplate.
The circularly polarizing plate has a function of isolator which blocks out reflection light when the circularly polarizing light which is changed from incident light passes through the plate and is reflected on the reflection surface.

Item numberSB-RETAX-5L-1/4λ-20
