Lens design for blind spot detection

IB/E optics was tasked with the project to create a three-lens system for less than ten Euros per series. Among others, the company’s specification requirements included low level of distortion and a maximum field angle of 126°. After several approaches, a three-lens system with a diffractive surface was chosen and realized through an injection-compression process.


With regards to the coating, numerous variants were examined and tested. The system only works within the NIR-range and features an opening of 1:2.4 with a distortion level of less than two percent at 126°.
