When I started collecting these files, I had in mind the objectives for typical upright microscopes, objectives like the 40X one in US04379623-1. I’ve used this kind of file for baseline designs in various proposals and other concept development tasks. I added other design types more out of curiosity. Notable designs include: low magnification inspection microscope (US04501474-1) several immersion objectives with super-high NA (US05532878-1, US08199408-1), and some intriguing catadioptric designs, also with very high NA (US07633675-1). Most of the models include only the objective, but some, such as US07158310-6, include the field lens, too.

If you find these files interesting or helpful, please contact me via e-mail or the comments section. Even better, please join the collaboration by contributing some of your own design files.
