Wave plates for lasers are used to change the direction of laser polarization and improve processing homogeneity, while quartz crystal windows are used to protect against laser damage and prevent contamination. We provide long life and highly reliable wave plates and quartz windows with excellent laser resistance utilizing our superior substrate processing, coating, and bonding technologies.

① We can provide wave plates and quartz windows that transmit over a wide wavelength range from 150 nm to the infrared wavelength band.

② We also offer coatings that are highly resistant to lasers, with design and manufacturing methods that take laser damage into account.

③ To prevent deterioration of the adhesive by lasers, optical contact type wave plates without adhesive are also available for adhesive type wave plates.
The number of coatings can be reduced, and laser resistance can be improved compared to the conventional air gap type.
