We welcome you back to our technical series on the Concepts in Light and Optics. In our previous 3 articles we discussed different types of lens configurations, the manner in which they manipulate light, as well as, the terminology and specifications used by optical fabricators to define the quality and precision of their lenses. Building on this knowledge, we’ll now explore one specific lens design that provides significant benefits over those with standard spherical radii. These unique optics are called aspheres. As you will see throughout this article, while complicated in design and often difficult to manufacture, aspheric lenses solve many...

Esco Optics representatives will be attending SPIE OptiFab this week taking place at the Rochester Riverside Convention Center. We enjoy the opportunity to connect with colleagues from around the world in the hub of optics in Rochester, NY. Each year the bright minds in optical manufacturing connect, share and inspire new innovations and procedures that we love being a part of. Hope to see you this week. 

World Space Week came to a close on Tuesday. This year’s theme, Exploring New Worlds in Space, casts an outward, and upward, view—and we’re proud to provide the custom optics that help explorers see further. We’ve enjoyed sharing some of our thoughts, ideas, and innovations with you through the week, and we hope you enjoyed our posts.  We covered a lot of topics between October 4 and October 10, from why we’re geeking out over World Space Week to what it might be like if we never landed on the moon. Ever wonder about sharks with lasers and precision measurements from...
