Radiometer – The original Crookes' Radiometer

The radiometer, also known as Crookes' radiometer, is one of the most fascinating scientific objects of the 19th century. Developed by William Crookes in 1873, its construction makes light energy visible: when light hits the vanes suspended in the glass bulb, the rotor begins to turn – at different speeds depending on the intensity of the radiation.

The combination of physical phenomenon and timeless design makes the radiometer an extraordinary object for a desk, shelf, or windowsill. The floating movement of the vanes is both calming and mysterious, repeatedly drawing attention.

Made of glass, the radiometer combines scientific history with decorative elegance. It reacts to various light sources, especially infrared thermal radiation, and serves not only as a stylish design object but also as a clear demonstration model for physical principles.
