Project-Based Learning Case in Photonics Engineering Course: Implementation of a Spectrophotometer

Abstract

A project-based teaching course for postgraduate students in the field of Photonics Engineering is based on the implementation of a Spectrophotometer. Hard and soft skills are evaluated in the implementation with an auto-evaluation criteria. Comments and questions should be directed to the OSA Conference Papers staff

Viking Spectrophotometer: A Home-Built, Simple, and Cost-Efficient Absorption and Fluorescence Spectrophotometer for Education in Chemistry

“…Previously, self-built solutions for absorption and fluorescence spectrophotometers were presented. , Among those, the dominant majority involved UV–vis absorption spectrophotometers with only a handful of them involving self-built fluorescence spectrophotometers and even fewer considered the combination of both. A combined absorption and fluorescence spectroscopy for education was reported previously by Patterson et al and Pokrzywnicka et al The approach of Patterson et al was costly (∼2000 USD), since they used commercial spectrographs and accessories.…”

“…A recent review compared different published designs based on, e.g., commercially available plastic components (e.g., LEGO parts) − or 3D-printed parts. ,− LEGO blocks are convenient to assemble due to the overall rigidity and intrinsic regular arrangement of their studs, which ultimately provides an experience similar to the use of an optical rail, as adopted in many high schools. The angular and positional constraints, however, do limit the flexibility to move and (mis)­align optics.…”
