High power 850nm Superluminescence Light Emitting Diodes for FOG

The device is PN junction electroluminescence device by forward bias. Electron of invert distribution in active region from conduction band transit to valence band at forward current is injected, and release out photon after with hole compound. When light is transmitted in given cavity and light gain is obtained, thereby amplified spontaneous radiation light is achieved.

Product Features

Use method

The Modules can normally operating after correctly connecting according to corresponding base pin arrange. Optical output is achieved at injecting bias current to SLD. Thermistor reflect temperature change in the modules, resistor value of thermistor can assure to 10 kΩ by adjusting input current of cooler, operating temperature of SLD die can automatically adjusted by temperature control circuit, to ensure the modules reliable operation.

Warning contents

When SLD is used, not add more maximum nominal value of the modules, to avoiding damage or breakage module.Avoid electrostatic percussive in transport、storage and use.When is soldering, soldering temperature less than 245℃, soldering time less than 5s, and the iron must cut off power source.
