Make the hole the same size as the lens diameter. See the following to see how this does also depend on the sensing method used.
1. To use light through a hole
Make hole the same size as the lens diameter to secure corridors of light regardless of the through-beam or the reflective.
When holes are smaller than the lens diameters, the rated sensing distance might not be satisfied because the amount of light decreases.
