Our best-selling pen laser pointer: bright green, slim, on AAA batteries
Green laser pen with a pattern cap for shapes and figures
Three laser pens, three colours: green, red and violet
The human eye is most sensitive to green light. That is why a green laser pointer at 532 nm looks so much brighter than a red or violet one with the same class 2 output. For anything beyond a meeting room – pointing at a roof, showing someone a star, moving pigeons off a field at dusk – green is the colour to choose. Indoors the dot is crisp and easy to follow on a wall, a whiteboard or a projector screen.
Every green laser on this page is a Starlight Lasers model with an output up to 1 mW, laser class 2 – the class intended for sale to the public in the UK. There are two families. The green laser pens are slim, pen-shaped pointers with a clip that run on two AAA batteries. The green Pro models have an aluminium body, a rechargeable lithium-ion cell and a charger in the box. Both families share the same 532 nm colour and the same indicative range; the difference is in battery, size and finish.

Green lasers are bright, which is exactly why you should treat them with respect: never aim at eyes, people, animals' eyes, vehicles or aircraft, and keep them away from children.
