Freeform polymer optics can unlock new ways to reduce part count, weight, and system footprint—but traditional optical design and metrology are often not able to keep up with these new optics. FTI has decades of experience with designing, crafting, and measuring innovative freeform optics.  #### FTI President Dr. Nelson Claytor was a featured speaker on Manufacturing Methods at the 2024 Optica Freeform Optics Industry Summit.  [Download the Presentation](https://www.fresneltech.com/optica-freeform-summit-slides?hsLang=en) ## FTI Freeform Optics Capabilities Freeform optics have emerged as a promising design technique to minimize size and weight of complex optical systems. The optics industry is still working to standardize on methods for designing, specifying, and measuring freeform optics.  FTI offers proven experience in manufacturing and prototyping of freeform optics in polymers, metals, and IR crystals via diamond turning and milling, as well as in polymer molding and moldmaking. The manufacturing of freeform optics presents new and significant challenges in design, fabrication, and measurement. FTI uses our expertise and our in-house metrology lab to ensure that our freeform optics meet the high standard of precision that is a chief characteristic of all FTI products.  [Discuss Your Freeform Optics Project](https://www.fresneltech.com/freeform?hsLang=en#project-form) - Single point diamond turning for prototyping and small volume freeform manufacturing - Profilometry, functional testing, and process controls for QA in prototyping and volume production - Diamond machined aluminum freeform mirrors and freeform IR crystal optics - Precision injection molded polymer optics, with prototyping via diamond machining ## Recent Freeform Optics Projects #### Cubic phase plate for improved depth of field in a computational imaging platform. #### Laser scanning optical array for home-use aesthetic dermatological device. An injection-molded freeform optic made up of twenty-four non-rotationally symmetric optical surfaces, which makes a line of twelve focused spots when rotated in front of a fixed near infrared diode laser. This configuration significantly reduced the size and weight of the device. #### Atoroidal lens for correcting keystone effect in a tightly folded projection system. ![Cubic Phase web image](https://www.fresneltech.com/hs-fs/hubfs/Cubic%20Phase%20web%20image.jpg?width=640&height=480&name=Cubic%20Phase%20web%20image.jpg) ![Aspheres vertical-1](https://www.fresneltech.com/hs-fs/hubfs/Aspheres%20vertical-1.png?width=250&height=300&name=Aspheres%20vertical-1.png) ![Asteroid Lens web image](https://www.fresneltech.com/hs-fs/hubfs/Asteroid%20Lens%20web%20image.jpg?width=1280&height=960&name=Asteroid%20Lens%20web%20image.jpg) ## Discuss Your Project ***FTI respects the proprietary nature of your project.
