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.

basic information
**Features** - The optical pickup uses a 790nm laser for CD recording and playback, and a 650nm laser for DVD recording and playback. - The emitted light is transmitted and reflected according to the polarization components by filters and mirrors. This allows for the separation and synthesis of the optical path, directing it to the disk or detector PD. - Optimal filters are created according to user requirements for transmission and reflection rates, polarization, phase difference, etc. - Support is also available for next-generation high-density optical discs using a 405nm violet-blue laser.
