Mini Green Laser Diode Dot Module, 515–520 nm, 5 mW, 3–5 V

This mini green laser diode module emits a highly visible dot beam at a wavelength of 515–520 nm. Powered by a standard 3–5 V DC supply, its compact footprint allows for straightforward integration into embedded hardware and custom equipment. It is well suited to students, makers, and engineers developing robotics, alignment aids, and machine vision projects.

High-visibility green beam

The module projects a crisp green laser dot at 515–520 nm with an output power of up to 5 mW (Class 3R). It achieves a tight spot size of 10 mm or less at a distance of approximately 8 metres.

Compact embedded design

Measuring approximately 6 × 10.5 mm, the module is mounted on a compact PCB for easy installation into space-constrained projects. It operates on 3–5 V DC with an operating current of up to 300 mA.

Versatile project applications

Designed for aiming, positioning, machine vision, and optical alignment across laboratory and DIY setups. The diode module operates reliably within an ambient temperature range of 15°C to 40°C.

Operational safety advice

As a Class 3R laser device, direct eye exposure must be avoided and the beam must never be directed toward people, vehicles, or aircraft. The use of appropriate laser safety eyewear is recommended during assembly and testing.
