Lenses That Unveil the Cosmos

In the 17th century, Christiaan and Constantijn Huygens ground their own telescope lenses. With these lenses, Christiaan discovered Saturn's moon Titan and the rings of Saturn. Their fascination with astronomy led to groundbreaking discoveries.

The Huygens brothers etched their names into their self-ground lenses—undeniable masterpieces of science and craftsmanship. Their work marked the Dutch Golden Age of astronomy.

Self-ground telescope lenses brought Christiaan Huygens worldwide fame, from discovering Titan to understanding Saturn's rings. For a man of his status, engaging in lens-grinding was unusual, but their precision work made history.
