C/CS Mount Adapter for DIN Threaded Microscope Objectives

thingiverse

This is an expedient adapter to attach a microscope objective to a c/cs mount camera/sensor like the new Raspberry Pi HQ camera mount. I've managed to cobble together this adapter with no real understanding of optics, so it may not be optimal in any way. Nonetheless, you must print the adapter using a very small layer size to ensure the threads function properly. Additionally, thoroughly clean the piece before mounting to prevent loose particles from damaging your optics or sensor. Attached is an image I took using a 5x magnification lens, although I have no idea what the actual optical magnification is. For lower magnifications, you will typically need a longer tube; in this case, you can customize the length of the tube within the FreeCAD file if required. Microscope objectives are generally designed for a 160mm tube, but that's quite cumbersome for my needs.
