Focal Length

Pixy Software

Hi, all

Does anyone know the focal length of the original Pixy lens?

Another question:
The image sensor of Pixy is 1/4’’, but could I replace it with the one designed for 1/2 image sensor or 1/3 image sensor?

The focal length is 2.8mm.

You can mix up lenses like this as long as the lens you use is for a bigger sized sensor. It’s not optimal because you’re “wasting photons”, but it should work fine. Also make sure your lens has a IR cut filter.

hope this helps!

Thanks a lot, Rich, this is quite useful.
