More and more precise camera and projection systems are required in automotive interior and exterior lighting. Headlamps for adaptive driving beams and projections onto the road need an accurate and sharp image. AR applications and the projection of warning notices require such a high quality that the field of view and the distance help with the accurate calculation.

With Zemax OpticStudio you can accurately calculate automotive lighting systems, e.g. the projection lens for a headlamp. Starting the lens design and optimization in the sequential mode, the Field Data Editor will help you to define the field of view.



Suppose you want a solution that automatically sets the radius of the object plane equal to the Petzval curvature. Of course, always start by checking that a solve isn’t already supported before writing a macro! The existing PETC macro solution (linked below) calculates the Petzval curvature of the system and returns the value to OpticStudio.

In the non-sequential mode, you can then define additional sources, detectors and apertures for lighting regulations to simulate the lighting function.
