This contains PDF shop drawings and STEP model files that can be used to fabricate and/or check the custom mechanical parts, and custom detection system lenses, that were designed at Janelia (almost everything except the Thorlabs gantry/cage and Jenoptik Optical Systems lens tubes for the custom excitation optics). These parts can also be purchased from previously used vendors, referencing quotes posted here.
