This paper explores the development and implementation of a remote spectrometry laboratory as part of the “Online laboratories for science education and training” (OnLabEdu) project in Austrian schools. This initiative responds to the increasing demand for remote learning by creating innovative, user-friendly online labs that facilitate the practical teaching of science through internet-managed remote labs. The spectrometry lab, specifically, employs spectrograph and color filters to teach fundamental concepts of light and spectrum, enabling varied experiments remotely. Initial outcomes indicate a significant step towards enhancing science education's accessibility and engagement, emphasizing low-maintenance and flexible experimental setups. This approach underscores a broader move to integrate technology into practical science education, offering scalable and innovative solutions to traditional educational challenges.
