Super Broadband Wave plate SB-RETAX Super Broadband - RETAX Constant linear retardance is realized for light of any wavelength ranging form visible (VIS) to near infrared (NIR) when linear polarized light passes through this waveplate SB-RETAX. This SB-RETAX is fabricated by laminating birefringent films within optical glass substrates.

Type of Products SB-RETAX realizes constant linear retardance for light of any wavelength in broadband, when linear polarized light passes through SB-RETAX. Wavelength ranges depend on the number of film layers, SB-RETAX has 2 type of lineup such as 3 layer and 5 layer. The Number of films Wavelength range Tolerance of retardance Glass material Multi layer coating on both sides 【 P/No. 】 SB-RETAX ↑ Film layer Wavelength range of 3L type Composition of Products SB-RETAX is fabricated by laminating birefringent films within optical glass substrates. Composition example of 5 layer Glass substrates...

1/4 waveplate realizes quarter retardance to an incident light. A circularly polarizing plate is realized when 1/4 waveplate is combined with a linear polarizer. A circularly polarizing plate has a function of isolator to block reflection light from a reflection plane, in case an incident light goes into the circularly polarizing plate and the outgoing light is reflected on the reflection plane and goes back into the circularly polarizing plate.
