Educational trail of the Czech Academy of Sciences institutes in Ládví, Phase I: Spectroscope

The J. Heyrovský Institute of Physical Chemistry has chosen a unique optical spectroscope as its contribution to the trail, which will allow visitors to see the decomposition of sunlight into a spectrum of visible colors, including Fraunhofer lines, which reveal the presence of chemical elements in solar radiation. The exhibit will take the form of a sturdy vertical column, the upper part of which will be optically focused on the sky. An optical lens, slit, and diffraction grating will together create an internal spectral path ending in an observation eyepiece. Visitors will thus see the actual spectrum of sunlight, including the characteristic dark absorption bands – Fraunhofer lines. In the context of the above, the exhibit will be accompanied by a text that will explain in simple terms the principle of spectroscopy, its importance for terrestrial science, and for the exploration of space. The proposed solution combines aesthetic value with scientific accuracy and mechanical durability for long-term outdoor operation. The use of passive optics ensures functionality even in diffused light. The object will be maintenance-free, vandal-proof, and require no power supply. It will serve as both an educational point and a sculptural element that will visually and functionally enrich the urban environment.
