On Thursday the 15th of February, Tim van de Ven from Demcon hosted an interesting lunch, giving insights into a representative project undertaken by the company. Tim guided us through a specific project focused on aligning interferometer heads, which are used for measurements with sub-nanometer precision and thus requiring very precise alignment. The lecture covered various approaches undertaken during the project to fixate the interferometer heads, along with the solutions Tim came up with to address hysteresis and overconstraints. Demcon is a unique High-Tech Engineering company, with one of its primary offices located in Delft! Every year Demcon hosts an in-house day so make sure to check this out!
