Laboratory of Physics (C207/C208)

The Laboratory of Physics imparts the physical basics of engineering science by means of meaningful experimental setups that provide valid quantitative measurement results. The focus is on kinematics, dynamics, vibration theory, fluid mechanics, thermodynamics, acoustics and optics. The laboratory has a separate laser protection area (room C208) where experiments with laser radiation are carried out.

Goals and idea

Physical connections are made accessible through clear examples from practice. The laws taught in the lecture can be applied directly. The laws of nature can be directly experienced.

News from the lab

Recently, the THI has been equipped with a 250 mm diameter integrating sphere, which is calibrated to luminous flux together with the MAS40 spectrometer. A Peltier cooler, which is controlled by the SpecWin Pro spectrometer software, and a measuring current source enable fully automatic recording of temperature profiles of LEDs up to a diameter of 75 mm. The data is automatically generated and stored for a freely configurable measurement sequence.
