I watched a presentation today and I was sold to build an openflexure microscope.The printing and fasteners and Pi seem clear. But I have no idea about the optics.
The most important seems to be the objective and in the help I see ‘or obtained very cheaply on AliExpress’ (I pasted at the end the full quote for completeness).
The issue is finding such an product on aliExpress when you don’t really know anything about optics.
Does anybody has a decent link or a BOM with a link to an AliExpress item?
I’m afraid I’ll buy a part that will not work at all.
- Tube length: 160mm
- Correction: Plan
- Magnification: 4x-100x
- Suppliers: Comar Optics, ThorLabs, Olympus, Nikon, Zeiss, Sunlight Optical via AliExpress
The microscope should accept most RMS-threaded objective lenses, and depending on whether you use the sample riser it will use either 35mm or 45mm parfocal distance. These objectives can typically be scavenged from old equipment, or obtained very cheaply on AliExpress. We recommend going for Plan or Semi-Plan corrected lenses at 40x, and definitely Plan corrected or better at 100x.
