Concepts in Light and Optics - Lenses - Part 1

Posted by Bill Hill on

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...

Got Power?!

Posted by Ron Schulmerich on

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...

Concepts in Light and Optics – Optical Specifications – Plano Optics

Posted by Bill Hill on

In our previous articles we learned that optical materials are defined by their ability to refract and disperse light, as well as, the physical characteristics of the material itself. Using these properties, an optical designer determines which material, or often times several different materials, best suit the intended purpose of their system. But choosing a material is only the first step in the process. More often than not, a simple polished surface that is smooth and defect free to the unaided eye, would cause any number of unwanted optical effects when assembled into a fully integrated system. It is important...

Concepts in Light and Optics – Interferometry

Posted by Bill Hill on

We’ve reached a crossroads in our discussion of the concepts in light and optics.  Previously, we learned that optical materials are manufactured to have very specific refractive and dispersive properties, and it is these characteristics that optical designers rely upon to manipulate light to a desired purpose.  We’ve also discussed that material properties such as stress, fluorescence, coefficient of thermal expansion and homogeneity play a large role in how an optic behaves when incorporated into a fully integrated system.  But once an appropriate material has been chosen, whether for use as a lens, window, prism, or mirror (among others), how...
