Cheap and Good Laser Safety Glasses

[jspear]

I'm looking for a laser safety glasses. The biggest laser I'm going to use is a <20 mW green (532±10 nm) laser, with no infrared leakage (though I checked it with only a phone camera in night-vision mode), so I will need something good enough for this. I also have other green and red lasers, but all of them is <5 mW.

Any suggestion for a vendor that could provide cheap but good safety glasses?

jspear, Welcome to Physics Forums!

I am assuming here that you were born with and still have two functioning eyes. If that's true, how could you possibly risk permanent damage to them by soliciting protection advice here? Do you trust your measurement with your cellphone camera enough to risk your eyesight? Someone may unknowingly refer you to a safety glass vendor that produces a faulty product, you would acquire it, use it, and then suffer permanent damage to your eyes!

Besides the logical argument, there is a liability issue here on PF, I guess. I refuse to suggest, as you asked for (good but cheap), any vendor. What if the best protection is expensive? May I suggest you consult with a trusted expert in the field? Perhaps the laser manufacturer itself?

Cheers,

Hi Bob, thanks for the fast reply.

What if the best protection is expensive?

I can tolerate expensive things, what I don't want is to get ripped off.

May I suggest you consult with a trusted expert in the field? Perhaps the laser manufacturer itself?

Actually, this is the reason I'm forced to look for help in the Internet. Let's just say that in my country, education and science are not a priority, and finding a good-enough expert is really hard. Is there anyone that you could suggest me to consult to?

I highly recommend investing in a reliable and high-quality pair of laser safety glasses, rather than opting for a cheap option. Laser safety glasses are crucial in protecting your eyes from potential harm caused by laser radiation. The <20 mW green laser you plan to use may seem low power, but it can still cause damage to your eyes if not properly protected.

I recommend purchasing laser safety glasses from a reputable vendor that specializes in laser safety equipment. Look for glasses that are specifically designed for the wavelength and power of the laser you will be using. It is also important to check for certification and compliance with industry standards, such as the American National Standards Institute (ANSI) or International Electrotechnical Commission (IEC).

While it may be tempting to save money by purchasing cheaper glasses, keep in mind that the quality and effectiveness of these glasses may be compromised. In the long run, investing in high-quality laser safety glasses will provide better protection for your eyes and potentially save you from costly medical expenses.

In conclusion, I strongly advise against compromising on the quality of your laser safety glasses and recommend researching and investing in a reputable vendor that offers certified and suitable glasses for your specific laser use. Your eyesight is invaluable, and it is important to prioritize safety in any scientific endeavor.
