RIMSA, established by Palmino Longoni in 1936, was originally involved in the design and development of pantograph lamps. In the 80’s, RIMSA began focusing closely on the surgical lighting sector and, in 1983, developed its own first surgical light.
In 2002, RIMSA patented the world’s first LED operating theatre lamp, at a time when this technology was still in its infancy. In 2017, thanks to the design and development of Unica, RIMSA's ultimate surgical light, the attainment of a further achievement was made possible: glare free effect on a surgical lights.
