Overview
ø3.55±0.1
The LNC803PS is a GaAlAs laser diode which provides stable,
continuous, single mode oscillation of near infrared light at room
temperature. This product can be used in a wide range of light source
applications, including laser printers, facsimiles, optical disk memory,
and optical information devices.
