Two Position Zoom Lens



Autonomous vehicle requires lightweight lens to image at two unique focal lengths.


The required lens was exposed to heavy shock and vibration. Additionally, the lens had size constraints with a forced geometry, difficult weight restrictions, and ultra-low power consumption.


Durability:The lens had a very durable and ruggedized design.
Innovation::The design had a folded optical solution which swings 90° to achieve two positions.
Mechanics:Fast mechanical switch from 100mm to 300mm focal length (latch system). Particular attention paid to the overall center of gravity of the optical lens system.
Design:The final optical design had very few elements to maximize light transmission.  It also had a very high numerical aperture (low f-number) for low-light conditions.
