Thank you, https://www.physicsforums.com/members/sourabrata-bose.625200/

Thank you, Pixel. I think that this is the best solution. Using coated lens. Thank you, Domullus. But the only mirrors in the laser beam are inside the laser and I can't dismount it.

Thanks Domullus. Great idea! I will try it. :wink:

No. That is illumination that we are using. We only need the laser spot so only use environment lighting.

Ah! Ok. I haven't seen that button :oops: :smile::smile::smile: That is the image. I need only the main spot of the laser but there are a secondary reflection...

Thanks berkeman. Maybe, also I think that can be a reflexion in camera optics. Or a second reflexion in a deeper layer of the paint. The first layers of paint can have some index of transmission until the layer of a second reflexion. I can't reproduce the effect for the moment because I...

Thanks a lot! :-)

The laser is pointing to a painted metal surface and in parallel to laser and similar distance is located the camera. The resulting image of the camera have two laser spot. one es very big. The other spot is close to the first one and much smaller. Sorry, but I can't upload the image because i...

Hello everyone. I have a question about Optics and I place here because I don't know if there are a specific thread. I am using a laser beam to calibrate position of several cameras. But instead of to have one spot in the image I have two spot. One of them is smaller of the other. I presume...

Both of them.
