HI-RETAX is the compensator glass which bonded a wavelength film having the birefringence together by holding between the substrate such as optical glass which optical characteristics is excellent. Rich types such as 1/4 wavelength, 1/2 wavelength and full wavelength (sensitive color) have been prepared. HI-RETAX is the compensator that improved quality more than RETAX. • There is little change in the phase difference at the high temperature (approximately 70 °C). • There is not almost place difference in the plane. • The sensitive color plate (full wavelength) is seen the color similar to crystal compensator and mica compensator to be observed under polarized light. Products list HI-RETAX-1/4A The case in which the incident light of linear polarization is changed to circularly polarized light. HI-RETAX-1/2A The case in which incident light is rotated for vibrations direction 90 degrees. Suitable for the sensitive colour plate. When the sensitive color plate is put between two polarizing plates, the light passed them is vivid blue-purple coler as an interference light. Specification of standard product Glass It is possible to satisfy customer's request for special specification.
