Two Position Zoom Lens

APPLICATION:

 

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

CHALLENGE:

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.

SOLUTION:

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.
