The "crystal wavelength plate" is an optical element that utilizes the birefringence of crystal to create a phase difference in light, enabling circular and linear polarization. It is used in optical pickups for DVDs, reading devices such as digital copiers, and optical communications. Additionally, crystal wavelength plates for projectors can also be manufactured. 【Features】 ■ Optical element for circular and linear polarization ■ Crystal wavelength plates for projectors can also be manufactured ■ Usable in reading devices such as optical pickups for DVDs and optical communications *For more details, please refer to the PDF document or feel free to contact us.
