Optical Ruler Series

If you've stopped by Fresnel Technologies Inc's booth at a trade show, you've likely collected or seen one of our optical ruler giveaways. Each ruler features optics that showcase Fresnel Technologies’ design and manufacturing expertise. The optical elements of each individual ruler go far beyond just fresnel lenses— just like our company's capabilities!

Our optical ruler series includes three current versions, with a fourth to be unveiled just after 2022 SPIE BiOS and Photonics West.

The sleeve color is specific to the Ruler version, as indicated in the picture below. Check out the optical elements and details of each Ruler. Collect them all and think FTI for all your innovative polymer optics!
