This post is an initial evaluation of the community microscope (with USB webcam- reverse lens).
Components: -Camera: USB 2.0 webcam with reverse lens -Image: Microscope Camera Calibration Slide (Minimum division: 0.01mm (10 um)) -Computer: Raspberry Pi -Software: fswebcam for picture with matplotlib for annotation
My resolution estimate (for the USB 2.0 webcam and reverse lens) is approximately 100 pixels for every 50 microns or 2 pixels /micron. Please double check and recommend alternate ways to state/measure resolution!!
Note that this is a first review and it's possible that different techniques or materials may provide different results.
