What is the range of a green laser pointer?
Visible laser pointers (400–700 nm) operating at less than 1 mW power are Class 2 or II, and visible laser pointers operating with 1–5 mW power are Class 3A or IIIa….Colors and wavelengths.
| Color | Wavelength(s) |
|---|---|
| Yellow | 589 nm, 593 nm |
| Green | 532 nm, 515/520 nm |
| Blue | 450 nm, 473nm, 488 nm |
| Violet | 405 nm |
How far will a blue laser go?
blue at 445 nm. Here is a comparison of two 1 watt handheld lasers. One is green at 532 nm (88\% apparent brightness) and the other is blue at 445 nm (3\% apparent brightness). The green has a visual hazard distance of 25.5 NM, while the exact same laser in blue has a visual hazard distance of only 4.8 NM.
Is a green laser stronger than a red laser?
So, you could have a red and green pointer, both with a power rating of 1mW, but the green one would look about 30 times as bright. It strengthens the impression that green lasers are significantly more powerful than red.
How far can a 10000mw green laser go?
5000 meters
Just gently press the switch button; you will notice a beam of strong green light sending out from the laser pen. With such a portable tool, you can point at any target as far as 5000 meters.
Which color laser is the strongest?
green lasers
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.
How far can a 500mw green laser go?
In total darkness we can see a <5mW 650nm laser around 500 – 1km away when it shines on a white surface. The divergence will make that projected dot 1km away a large dot that reach 20–30m in diameter, and very faint. Green YAG laser pointers at the same power, is in comperison visible up to 4–5km away.
What is 532 nm laser?
The 532 nm laser is one of the oldest and most established of diode pumped solid state lasers (DPSSLs). It revolutionized the laser community and the idea of an all solid state (as opposed to gas gain media) laser was turned into a potential commercial reality.
What is the best laser pointer color for visibility?
Whether blue, red, purple/violet, or a light color like yellow, green is the best at strength for visibility. For example, a 1 00mW green laser will literally be 5-7x brighter than a red or purple laser pointer of 100mW. So if you’re going for visibility, be sure to first and foremost consider green.
What is a green laser pointer used for?
For example, green laser pointers are used for astronomy, especially stargazing. The green laser is brighter, can also be visible during daytime, and the light can go for longer distances than red lasers.
What class does a 5MW laser pointer belong to?
5mW Laser Pointer belong to class llla. The 5mw green laser pointers are the safest power laser pointers to use. You can also use 5mw astronomy laser pointers for pointing purposes since the beam is still visible in dark lighting conditions.
What is the most powerful laser pointer in the world?
High power 50000mw laser pointer is the world’s most powerful laser pointer. 50000mW Green Beam Light Separate Crystal Laser Pointer Pen Black 50000mw 520nm Burning High Power Green Laser pointer kits GT – 990 UKing ZQ-j8 50000mw 445nm Blue Beam 3-Mode Zoomable 5-in-1 Laser Pointer Pen Kit Black
