I made a scanning laser microscope
I built a 3D printed, scanning laser confocal microscope so I could collect 3D surface topology and profilometry data! The microscope stage is based on an OpenFlexure "Delta" stage, and the confocal optics are constructed with a 3D printed body, some lenses, a 405nm laser, pinhole and photodiode. The microscope is controlled by a Raspberry Pi (which controls an arduino to move the steppers).
It's not beautiful, it takes forever to scan, and the images are of dubious quality... but it works!
