We demonstrate a simple and cost-efficient scanning confocal microscope setup
for use in advanced instructional physics laboratories. The setup is
constructed from readily available commercial products, and the implementation
of a 3D-printed flexure stage allows for further cost reduction and pedagogical
opportunity. Experiments exploring the thickness of a microscope slide and the
surface of solid objects with height variation are presented as foundational
components of undergraduate laboratory projects, and demonstrate the
capabilities of a confocal microscope. This system allows observation of key
components of a confocal microscope, including depth perception and data
acquisition via transverse scanning, making it an excellent pedagogical
resource
