Introduction

Lars Sandström is an inventor associated with Edmund Optics, Inc., in Philadelphia, Pennsylvania. His patent work concerns optical design, including the use of gradient refractive index technology to manage light and reduce optical aberrations.

Latest Patents

Sandström is named on 1 patent: “Optical Element with 3D Gradient Refractive Index.” The invention combines a traditional optical element with a gradient-index element whose refractive index varies from its center. The gradient-index element adjusts incident light from a second direction, helping collimate reflected light and reduce optical aberration. A dichroic coating between the elements reflects the incident light while transmitting light from the scene, and the traditional element reduces the gradient-index element’s optical power.

Career Highlights

Sandström’s listed patent reflects work on optical components that combine distinct materials and functions to improve light control. His association with Edmund Optics connects this invention to the company’s work in optical technologies.

Collaborations

Gary Pajer and Shawn Scarfo are identified as Sandström’s coworkers. The available information does not specify their roles in the patent or the extent of their collaboration.

Conclusion

Lars Sandström’s patent describes a layered optical design that uses a three-dimensional gradient refractive index and a dichroic coating to control light and address aberrations.
