How far can a 1mW green laser go?

Output power ( mw ) – A 200mW laser will be visible for more than 1 miles while a 1000mW laser pointer or more will also be visible for 10 miles. Wavelength ( nm ) – A green laser pointer is more visable than a red laser pointer .

Are green lasers illegal?

Those handheld green lasers pointers may not be as harmless as you thought. And yes, lasers above 5 mW are commercially available in the United States, but it is illegal to market them as Class IIIa devices. …

What color laser is the strongest?

As a general rule, green lasers are 532nm are 5-7X brighter than any other laser color, at the same power. Whether blue, red, purple/violet, or a light color like yellow, green is the best at strength for visibility.

Are blue lasers better than green?

Why is a green laser more expensive?

Green lasers are much more efficient and visible in areas of broad daylight and direct sunlight. Bear in mind, though that green lasers are typically higher in cost than red. This is because they have more components and better laser diodes than red.

How big is a 532 nm green laser?

532 nm green laser outputs 1W in a compact laser housing. 100 mW yellowish green laser at 542 nm; up to 500 mW greenish yellow laser at 561 nm and 555 nm. Ultra-stable CW green laser, laser output stability 0.5% and 0.25% over 24 hours, is available now.

What’s the range of a green laser pointer?

Generally, at night, a 5 mW green laser is useful up to several hundred meters. A 200 mW green laser is useful up to several kilometers. To be more specific than this you must determine the application and the surrounding environment. Beware of companies who simply claim a specific range for their lasers.

How many milliwatts does a green laser need?

While green laser light at <5 mW (less than 5 milliwatts) is considered eye safe for momentary exposure, it takes as much as 300 mW of invisible IR (infrared) light to produce this. An IR filter is crucial in order to protect your eyes, as it prevents the IR light from escaping along with the green light.

What can you do with a 200MW laser pointer?

200mW Lasers is excellent in laser cutting and as laser flashlights. People also use 200mW Green Laser Pointers as Kaleidoscopic Laser Pointers when they in disco. 200mW Laser Pointers in LaserPointerPro are professional with reasonable price!
