Super wide 160° FOV for MEKRA

The job was rather difficult. MEKRA LANG AG , a traditional automotiv vendor , wanted to get rid of the big mirrors for trucks. Several experts from electronics, optics ( IB/E optics ) and mechanics came together to  try out, what is possible. This was in early 2002 for tose who wonder. IB/E designed a hybrid lens consisting of one glass and 4 plastic  aspheres, one with a diffractiv surface to get rid of the temperature drift plastic has. The lens had to be  rather small to fit into a gas filled housing , watereproof IP65.
