Does anyone know a USB camera which has focus (provides sharp images) starting at 2cm maximum 5cm distance from the front of the lense?

Not a webcam, more for tinkering, like https://www.ebay.de/itm/176974679649?_skw=usb+camera&itmmeta=01K1D7BGFWMTMNKNDFNAE23R6D&hash=item2934834e61:g:55oAAOSw-1xn7Oi9

The data in the usual webshops hardly mentions this technical data.

Background: I want to try some OCR on a Ferraris power meter. (I have the led based method detecting the pass of the red bar. Want to try OCR now.)
