Lens Design for Blind Spot Detection

IB/E Optics was tasked with the project to create a 3-lens system for less than 10 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 3-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 and opening of 1:2.4 with a distortion level of less than 2% at 126°.
