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 else can I help you with?
What is the best color of laser pointer for cats?
The best color of laser pointer for cats is typically red or green, as these colors are most visible to cats and can engage them effectively in play.
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
What type of laser pointer works on an lcd?
A laser pointer that operates on an LCD typically uses a red laser, as LCD screens are sensitive to certain wavelengths of light. Red lasers, usually around 630-670 nm, are less likely to cause damage or interfere with the display compared to other colors. It's important to ensure that the laser pointer is used at a safe distance to avoid potential harm to the eyes or the screen itself. Always follow safety guidelines when using a laser pointer around electronic devices.
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.
How do you make a laser pointer on the Open Office?
To create a laser pointer effect in OpenOffice, you can use the presentation tool, Impress. First, open your presentation slide, then start the slideshow by pressing F5. During the slideshow, you can activate the laser pointer by holding down the Ctrl key and clicking the left mouse button. This will change your cursor to a red dot, mimicking a laser pointer for highlighting specific areas during your presentation.
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.
