Thanks everyone for your input. It helps bring some ease of mind.

I am worried, but I'm not sure if I should go to the doctor since I at the moment don't see any issues with my vision. However, the worry may cause more damage as it has been bothering me all day knowing that someone at work may have damaged my vision. This just doesn't sit well with me and is...

Oh i'd wear goggles if I knew someone was going to shine it in my eyes. :yabbmad:

Is it possible I have damage that is un-noticable?

The actual product still has a warning label denoting that it is a Class IIIa laser and to not look directly at it.

Hey folks, At work today an employee shined a Class IIIa, 5 mW, 525 nm laser into my eye. Laser Specs: Model DPSS-5B Output Power Certified 4.0 ~ 5.0 mW Wavelength 532nm Dimension 12X31.3+/-0.5mm (without circuit) Beam Mode TEM00 Operation Mode CW Beam Diameter <1.5mm at aperture Beam...

Sorry here are the laser specs. Wavelength 650nm Power output >900mW Power Stability 5% The Output Beam diameter(mm) 6*3mm Divergence Angle(mrad) <4mrad Light central height 15mm It's Red

Sorry to hear you guys think I am trolling. All I know is that the individual on our group who has been in "charge" of the laser started to ignore the rules and regulations given to him by professors. He thinks it's "safe" in certain circumstances. Obviously from my research he's an idiot. I...

The material was reflective tape. This tape to be exact; 2 in. x 36 in. Reflective Tape-PN03440 at The Home Depot

While operating under Class 3 limits is it safe to assume that it's not going to be full power to cause potential diffused reflection danger? Sorry if I seem trivial. I just want to be safe. My teammates claimed it was safe.

Does turning down the power to about 50 mW turn the Class 4 into a Class 3?

Wow thanks for the quick reply! Glad to know all is well then. There were a lot of eyes looking at it. Just out of curiosity, what power would be required to cause danger with diffused reflection?

I want to thank you all for your information and replying. I have one more question concerning the Class 4 Laser. It has the ability to turn down the power, which was done to do a short presentation with the project it was being integrated with. The power was turned down to about 50 mW and was...

Trying to get as much power in return as possible for a photo diode.

I want reflect the beam back but a diffusive reflection. I don't want just the beam coming straight back to the laser. It needs to spread out coming back as shown in the drawing.

Hey guys, I'm just trying figuring out how to reflect a beam diffusivley. Here is an image to illustrate what I am trying to do; I'm not sure what material would be best for this kind of project. Any help and or suggestions would be appreciated. Thanks

Good news guys, I just visited the eye doctor and he took images of my retinas to verify that there was no damage. Lucky for me the eye doctor verified and assured that I have no damage in either eye. My teammates are not very smart and I need to have a serious chat with them. Apparently the...

Hey guys, I am fairly new to lasers and am still learning about how to be safe with them. At my college I am working with a team on a project where we are using a Class 4 laser. My teammates think that the reflection from a Class 4 is not dangerous, however I disagree from what I have read...
