Disperse the spectrum

Installation. Four stations with stepper motors, supports, and small-format dichroic glass pieces.

Disperse the spectrum is an installation that works with light and its relationship with matter. Starting from the study of a specific material—dichroic glass—the project develops a heterogeneous investigation into light spectra, diffractive interfaces, and wavelengths, but also into wonder and the spectres that lurk around us.

In this installation, four beams of light strike dichroic glass pieces that rotate slowly on themselves, driven by a small stepper motor. Each piece of glass splits the beam into two pure, complementary colors, which are projected in opposite directions and vary as the glass rotates. The mechanical movement also causes a slight vibration of the glass on its support, generating a continuous tinkling sound that becomes part of the piece’s sonic atmosphere. Viewers can move among the supports and light beams, and approach them to observe the materiality of the phenomenon up close.

Disperse the spectrum is part of an artistic research project on the spectral nature of light and images, developed with the support of El Graner, a center for dance and performing arts creation. The research stems from the optical properties of a specific material: dichroic glass, capable of splitting light into two simultaneous behaviors—selectively reflecting certain wavelengths while allowing others to pass through. This phenomenon of interference and selective dispersion of the visible spectrum has given rise to three installations, which explore this spectral nature of light from various registers.
