## Standard builds of the microscope
The list of parts below is pretty extensive and tries to explain all the various options - however, if you just want to build a "normal" version of the microscope, there are two versions we'd reccommend:
### Webcam-based microscope
The basic version of the microscope uses a webcam lens instead of a microscope objective - you still get a really nice focusing/sample translation stage, but with basic options. This version is great for school or hobby use, gets a resolution of about 2um or better, and is the cheapest to build. This is the version we usually build at workshops. For each microscope, you will need to print one copy of each of the following files:

This will need the nuts, bolts, etc. described below, plus a Raspberry Pi computer (any model will do) and Raspberry Pi camera module. No other optical bits are required, except an LED for illumination. If you want to mount the Raspberry Pi underneath the microscope (our preferred option), print ``microscope_stand.stl`` instead. If your Raspberry Pi is in a case already, you should print ``back_foot.stl`` so the microscope sits flat on a table. Newer camera modules include a white circular tool for unscrewing the lens. If you don't have one, you will need to print the lens gripper (marked as optional).
### High resolution microscope
The version of the microscope used for scientific or medical research generally requires a conventional objective lens. Most of the parts are the same, but the optics and sample mount are different. You will need one copy of each of the following files:

**For reflection illumination you will also need**
Additionally, you will need:
* an RMS threaded, finite-conjugates [objective lens](parts/optics/objective.md). These can be obtained from e.g. AliExpress. Depending on whether it is 35mm or 45mm from the "shoulder" of the lens to the sample, you may or may not need the sample riser. We almost always use 45mm "plan" corrected lenses, which do require the riser.
* a 12.7mm diameter, 50mm focal length [achromatic lens](parts/optics/tube_lens.md), e.g. ThorLabs ac127-050-a or generic equivalent.
