This laser uses a laser diode with a wavelength of about 638 nm, while usual red lasers uses 650 or 660 nm diodes. The human eye is more sensitive to 638 nm light than longer wavelengths, this means that this laser will appear brighter than most other red lasers, even with the same output power.

In contrast with our other orange-red laser, this laser uses a so called "single-mode" laser diode. This means that the beam is perfectly circular and looks cleaner, and the beam spread is very low meaning that it can lase further without losing its focus.

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.

NB No batteries are included! You can find batteries in the "Accessories" section of the store.

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.
