This is a hanheld laser with an optical power of around 250 mW. The laser wavelength is 450 nm, which makes a brilliant, deep blue color.

In contrast with our other blue lasers, this laser uses a so called "single-mode" laser diode. This means that the beam is perfectly circular with very little noise around the dot, and the beam spread is very low meaning that it can lase further without losing its focus.

This laser is strong enough to produce a clearly visible beam in dark and dim environments. It also has some burning power, it can for example ignite matches and pop balloons.

All in all this is a great laser, especially for beginners!

NB: No batteries or charger are included! Batteries can be purchased here.

The laser is sold and shipped partly disassembled to make it legal to import to most countries. Assembly is very simple and requires no tools.

DANGER: This laser is not a toy, it is capable of causing permanent blindness, as well as posing a skin damage - and fire hazard. NEVER, EVER point this laser at any person, animal or flammable material. We recommend that you obtain and use appropriate laser protection glasses while operating the laser.
