FreeForm Optical Design

Consider the possibilities of freeform design

  • We develop FreeForm optical designs to meet manufacturing specifications, perform final tolerance and flare analysis to ensure manufacturability
     

  • Freeform lenses allow high resolution, high-zoom, low distortion, and low light capable lenses in a very tiny form factor, which is valuable to many industries such as mobile phone cameras or self-driving auto

FreeForm Lens Manufacturing

Order production support to minimize manufacturing error

  • With our uVo software, we support Free-form lens production using standard 3-axis CNC diamond-turning technology
     

  • Based on our experience, the manufacturing of freeform elements and the production cost of such lenses are almost the same as with conventional rotationally symmetric lenses.
