Is the Focal Length: 2.9 mm? Where can I get any product data sheet for this lens shipped with Pixy?

Thanks for anyone can answer this in advance.

Hi Hui,

Here is some info on the lens:

  • M12
  • 2.8mm focal length
  • f2.0
  • IR coated
  • Everything at 3 inches and further from the lens is in focus, although you can focus on closer objects by adjusting the focus

We don’t have a datasheet to share, sorry.
