Prism is a handheld spectrometer built around a chip-scale detector array. The design is fully documented, from the optical layout and baffle geometry to the firmware and a step-by-step calibration procedure, so that a small lab can build, verify and improve it.
Revision C reduces stray light by roughly a third compared with revision B and adds a temperature-compensated reference channel. All design files are released under permissive licenses.
