Custom Optical Designs
Order a design according to your needs
-
We develop high-performance, high-yield imaging and illumination optical designs for niche and emerging industrial applications such as machine vision, leveraging our extensive Zemax macro library and years of experience in the industry
-
Our manufacturing partners promise streamlined manufacturing and delivery of the final products
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.
