Lens Compatible with Playstation PS2/PS3, PVR-802W Optical Lens Head Replacement Repair Parts
Features: Since prism is semi-reflecting, light beam can not goes through it completely, but reached the photo-diode through the lens. Due to the disc surface is uneven point to record data, so the reflected light will be in different directions; people define different direction of signal as "0" or "1", light-emitting diodes gets the data of "0", "1", and ultimately resolve them as the data we need. Specifications: Model: PVR-802W Excitation Mode: Electric excitation Operation Mode: Continuous Wavelength Range: Visible light Length: 4.8cm/1.88in Weight: 20g(approx.) Package Includes: 1 x Head
Product Features
- head mainly includes generator (also known as diode), semi-reflective prism, objective lens, lens and photoelectric diode.
- When head reads the data on disc, the light from generator goes through semi-reflecting prism and converges on the objective lens; lens will make into extremely tiny points on CD.
- head is a the essential part of CD drive, and also is the most sophisticated part.It is mainly used for data reading, so take special care when cleaning drive inside.
- Because of the reflection material on the disc, light will reflect back, through the objective lens, then illuminate on semi-reflecting prism.
