Now that we’ve covered the basic type of lens configurations and how, by design, lenses either converge (focus) or diverge light, we can begin to explore the various characteristics that define their physical shape. Overall, there are many parameters that govern the performance of a lens. As previously discussed, it is the specific optical properties of a given material, namely its refractive index and dispersion, that influence light’s behavior when passing between mediums. Opticians build upon these carefully controlled properties by generating highly precise curvature (radii) across the surface of their lenses. By combining this curvature in relation to a...

Dear friends, customers, vendors and competitors, We all know what it’s like to have your business in a groove…or a lull…or even a grind. During Esco’s greatest period of growth, we suffered a devastating tragedy. While we wait for our new facility to be completed, we have found ourselves in an ongoing grind. We have done well to support our continued growth in imperfect conditions, and have made it a point to expand overall market awareness. It has been my main goal to prove to our customers that Esco can handle any situation and rise above it. Since August of 2014, I...

We welcome our readers back to our continuing technical series on the Concepts of Light and Optics. So far we’ve examined the nature of light and how it propagates, the principles of refraction and dispersion, material characteristics, interferometry, as well as, the fundamental specifications of plano optics. Building on all of these discussions, we now move on to a topic that is at the heart of optical fabrication – lenses. Lenses represent the workhorse of most optical systems. Properly designed and manufactured, these essential elements manipulate light, allowing scientists to examine everything from the minute details of cellular structure using...

In an effort to lessen the impact of New Jersey’s unpredictable weather, Esco has chosen to be proactive in installing a 300kW generator that is our backup power source at 95 Chamberlain Road.  After the likes of hurricane Sandy and the recent winter storm Stella, we know that a contingency plan for power outages is a must! Our hope is that this addition will ease the effects of power outages during unexpected weather events! The generator will provide Esco uninterrupted power to protect and maintain our production and computer systems.  This backup plan assures our customers have continued service and...
