Violet Laser Pens – Blue/Purple 405 nm

Violet laser pens at 405 nm

Searching for a blue laser pen or a purple laser pointer? What most people mean is a violet laser at 405 nm. This wavelength gives a striking violet-blue dot and makes fluorescent materials light up, which makes it popular for demonstrations and specialist applications. It is not the colour for maximum range: the eye is much less sensitive to violet than to green, so the dot looks dimmer and is visible over a shorter distance.

Our violet range covers three levels. The pen-style AV-1 delivers 5–50 mW on two AAA batteries. The AVP-1 Pro and AVP-2 Pro Mini deliver 50–500 mW with a rechargeable cell and charger. The VEX-1000 Pro is a 500 mW high-power professional laser for experienced users. All violet lasers demand the same respect as green ones: the dim appearance does not reduce the eye hazard.

Tips for violet lasers

• Wear goggles rated for 405 nm; see our laser safety glasses guide.
• Never judge the hazard by how bright the dot looks.
• For star pointing or bird control choose a green laser pen instead.
• Want all three colours? Take the pen-style set or the Pro set.

Safety: class 3B lasers can injure the eye instantly, also via reflections. Never aim at people, animals, vehicles or aircraft, wear suitable laser safety goggles and keep the laser away from children. As the buyer you are responsible for complying with UK law. Read our laser safety guide before first use.
