A microscope is an optical instrument that can be used for magnification. It's often made up of multiple parts, including: * optics (lens, focus, calibration) * a camera * a lighting system * a moving stage to hold slides Community Microscope Kit We’ve developed a microscope kit you can build yourself - the result of many teams’ work coming together! Read more about the Community Microscope! ## Questions Questions can be either frequently asked questions, or "next step" challenges we're looking to solve. [questions:microscopes] ## Activities Activities show how to use this project, step by step. [activities:microscopes] ## Updates [notes:microscopes] ...
