Check the label. If it is marked "Class II", "Class IIIa", "Class 2" or "Class 3R", it is safe. All of those have power less than 5 milliwatts. The "Class II/Class 2" pointers are the safest--they are limited to 1 milliwatt. Do not use blue or green laser pointers as toys, even if they are rated Class 3R.

What is the Wavelength of a red laser pointer?
Typically, most pocket red laser pointers have wavelengths that range between 630nm and 680nm. A helium neon red laser pointer has a wavelength of 633nm.
Does a red laser pointer give cancer?
No.
Can a red laser pointer damage a cell phone?
No, it can't.
What are the manufacturing costs of laser pointer components?
The most important laser pointer components is the laser module . The costs for different colors of laser are different , about 1$ for red laser , 10$ for green laser and 200$ for blue laser . And the costs are keep going down.
How do you increase the power of a red laser pointer?
Well, I know how, but it's not a good idea as it will make the laser produce more ir radiation, which is not good for you at all. I recomend buying a new laser. techlasers.com is the best, i just bought the 125mW infiniti, and its amazing. Also,you can replace laser diodes inside the red laser pointer,laser diodes are available on freaklasers.com
How do you make a 100mW laser with a 5mW red laser pointer you can buy from dollarama?
Using lents or using electronic componets or both
What are the uses for a CW laser?
A continuous-wave laser, or CW laser, is part of many items. A laser pointer's red beam is an example of a CW laser. CW lasers are also used in holography.
Can you make a red laser pointer into a high powered laser?
The answer is pretty much "No." You can increase the power slightly, but if you go much beyond what it's designed for you'll burn out the laser diode.
What is the typical power of a green laser pointer in milliwatts?
A standard green laser pointer has a power of between 4 and 20 milliwatts. A red laser, for comparison, has a power of less than 5 milliwatts. The beam of a green laser can often be seen, while the beam of a red laser cannot be seen.
What makes cats go crazy over a red laser pointer?
Cats will chase and play with anything that moves quickly, it is part of their hunting instinct. Not everybody is agreed that such play is a good thing as the cat never gets the satisfaction of "winning" as there is nothing there to hold on to. This might cause behavioural problems in the long term.
Why does one use a red lens on spot light to hunt?
if you mean the red laser sight where its just like a laser pointer i would use it for airsoft or night hunting maybe rats or late eveining rbbit hunting
The light from a red laser pointer has a wavelength of about 600 nm If this laser has a power of 0.23 mW what is the momentum carried by a 4.9s pulse of this radiation?
