Laser Pointers

Even though there are many dangerous issues caused by abusing laser pointer 5000mw , laser pointers, handheld lasers or even portable lasers cannot be substituted while they are in serious need in those of high tech working fields. For instance, low powered red laser pointer is being used in classroom, to teach light and physics properties. Astronomy researchers and amateurs would choose the most visible green laser pointers to make star gazing, constellation observation and other celestial objects observation. Some of high powered handheld lasers might be even used for burning tests in practical use.

532 nm Laser Pointer are made using DPSS technology. Our standard range is available with powers of 1 mW ~ 130 mW. These green laser pointers have a long beam range, high brightness, high beam quality and a low price.

Laser pointers have become commonplace since they are an effective tool to aid in presentations and inexpensive. Many people are concerned that laser pointers will hurt their eyes if they look at the laser light. So can laser pointers hurt your eyes? If you look at a laser pointer for a few seconds should you be concerned?

Power Output is not the only safety factor for Green Laser Pointers

Infra red light (808nm) is pumped through a medium to create a High power green laser pointers . Is IR light is not visible, so there is no point at which the look away reflex can offer protection prior to injury. If a green laser pointer emits 808nm infra red light, it is not safe. LASER Classroom’s™ green laser pointers and LASER Blox™ are made with an IR filter which ensures that no IR escapes. Many of the 90% of green laser pointers tested by the NIST either do not contain a filter or contain a filter that is not fitted properly and allows leakage of IR 808nm laser light.

Green laser pointers are significantly brighter (about 60 times) than a red laser pointer and because of its unusual color it is much more noticeable. Just about everyone has a red laser pointer, but we're pretty sure you want to own the very best - and doing it with a green beam laser is the way to go.

The lightweight and optimal size of this green laser 500mw makes it easier to control compared to other laser pointers on the market. This high-powered laser is perfect for presentations, outdoors, business meetings, school projects, use as a pet toy, etc. This laser pointer is ideal for teachers, students, businessmen, public speakers, engineers, doctors, managers, and more.
