We are ramping up for Photonics West in San Francisco from January 30 – February 1 and we hope to connect with you there. Don't miss Esco's expanded presence at Booth #4244 in the North Hall. This year we'll give you a sneak peek inside our brand new manufacturing facility. Our new building not only expands our capabilities, but also provides more efficient workflows that allow us to get our optics to our customers faster. Our aspherical lens machining is a growing product line for Esco with its unparalleled precision and delivery time. Photonics West is a great time to discuss how we can collaborate with you to help your organization.  

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...
