The CTS-150 is a new high-resolution spectrometer that has been specially designed for use in research and teaching. As an open-source project, all information on the elements used is open, so that spare parts or extensions can be easily produced using a 3D printer and laser cutter if required. Both the arrangement and the design of the elements are kept simple and easy to understand in order to facilitate the teaching of learning content.
