650nm Laser Diode H1 A18

The laser head is composed of a light-emitting tube, condenser lens, and adjustable copper sleeve and it is assembled when delivered, the focal length of the lens is adjusted and glued by a strong glue stick, which can work directly after connecting to a 5 V dc power supply.

Working

The laser diode module works with Arduino together which contains Signal, GND and the middle pin indicates +5 V. The connection between Laser Diode Module and Arduino Uno where signal, GND, +5 V of Laser diode is connected to pin 8, GND, and 5 V respectively. 

Then, download the source code attached here and open it via Arduino software. Choose the correct board and port before uploading the code into the board. Upload the source code into Arduino Uno.

Application

Used for DIY or robots

Used for all kinds of level meters

Part of Spectroscopy

In laser test tools

In medical equipment positioning

Production of signal equipment

Limitation

This is a low-power laser device however as with all laser devices care should be taken when in use. We should never look directly into its beam or point the laser at another person because doing so may cause permanent eye damage.
