450nm Blue Laser Pointer - Adjustable Focus Handheld Presentation Pointer

450nm blue laser pointer with adjustable focus, built for presentations, lectures and stargazing. A handheld blue beam pointer with a focusing head, so you can tighten the dot for a screen at ten feet or open it out for a night sky. Compact enough for a laptop bag or a jacket pocket, with a grip shaped for long sessions rather than quick jabs.

The 450nm wavelength sits in the blue band, which reads clearly against dark backdrops — lecture theatres, planetarium sessions, evening site walks. Simple single-button operation with no menus to learn.

Who it suits

Lecturers and trainers working a large room, amateur astronomers picking constellations out for a group, and engineers or surveyors who point at things across a distance for a living.

Safety: A laser is not a toy. Never direct the beam at a person, an animal, a vehicle, or any aircraft. Do not look into the aperture or at the beam through optics. Keep away from children.
