Best laser pointer for optics lab?

AI Thread Summary
The discussion centers on finding a reliable laser pointer suitable for educational optics experiments, emphasizing safety and quality. Participants express concerns about the prevalence of untrustworthy Chinese products and seek recommendations for well-known brands. Key safety considerations include selecting lasers with a proper safety class, specifically Class 1 or 2, and ensuring they have an on-off button and a magnet. The importance of using visible wavelengths and proper safety behavior around lasers is also highlighted. Overall, the conversation underscores the need for quality and safety in educational laser applications.

I'm serching around the web to find the best laser poiter (with real safety class). the below one is the only thing that I could find:

Do you know any other brands suitable for educational goals? we need to use laser pointer for some experiments such as lenses experiment. Lasers should have on-off button, safe ray and magnet.

(There's many chinese products that I can't trust them!)

Thanks for the post! Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?
 
I'm searching for a well-known brand for safe laser pointer. Internet is full of chinese products! I thought maybe someone knows a good brand in his/her country.
 
Well, this is kind of a big question. Maybe you'll get some more help if you be more specific. What kind wavelength do you require? What kind of power?

"Safe" in terms of lasers is an interesting term. You'll probably want something in the visible wavelengths, with power low enough that the blink reflex will save you - so class 1 or 2. However, nothing can make up for proper safe behaviour around lasers.

If you buy a green laser, make sure it has the appropriate filter on it - green lasers are made by frequency doubling an IR laser, and really cheap laser pointers will tend to leave out the filter to remove the IR part.

Most lasers used in physics experiments aren't laser pointers.
 
I would like to use a pentaprism with some amount of magnification. The pentaprism will be used to reflect a real image at 90 degrees angle but I also want the reflected image to appear larger. The distance between the prism and the real image is about 70cm. The pentaprism has two reflecting sides (surfaces) with mirrored coating and two refracting sides. I understand that one of the four sides needs to be curved (spherical curvature) to achieve the magnification effect. But which of the...
