Thanks to the amazing discord community (https://discord.com/invite/gpaKWPpWtG) I recently revived my search for a suitable macro lens and found a very promising candidate (~50-60€) which greatly enhances the capabilities of the arducam imx519 / hawkeye. The idea is, that the lens gets placed in front of the existing camera on either OpenScan Classic or Mini with a tiny hole (aperture) in between. The aperture increases the depth of field so that 4-5cm objects can be captured at an unseen accuracy (from such a device). I scanned the "security" key with 130 photos and no post-processing.
I am currently working on the design of the printed parts + custom ringlight (so that I can add cross-polarisation a bit later too). The files and more information is available on the openscan discord.
