Optical components for optical pickups: filters and mirrors.
I will introduce representative examples regarding wavelength and structure.
The optical pickup uses a 790nm laser for CD recording and playback, and a 650nm laser for DVD recording and playback. The light emitted from each laser source is separated and combined by being transmitted and reflected according to polarization components through filters and mirrors, and is directed to the disk or detector PD.
