Test System for Medical Technology

The new functions of an operating light, such as an adjustable color temperature and a variable light field diameter, got the test ­engineers into hot water: they ­simply could not be verified with conventional measurement technology. Therefore, together with a light measurement specialist, they developed a new test stand ­including a partially automated measurement process.
