Demand for infrared optical elements has extended beyond just lens assemblies and hot/cold mirrors. Specifically, there is growing interest across the optical industry for bandpass filters, achromats, athermal elements, and polarizing waveplates. The demand spans all IR wavelength bands—near IR (0.75 µm to 1.4 µm), short-wavelength IR (1.4 µm to 3 µm), mid-wavelength IR (3 µm to 8 µm), and long-wavelength IR (8 µm to 15 µm). Advances in sensor and source technology, as well as a changing marketplace, are driving this growth. Demand from three industries stands out as particularly noteworthy:Read More >
Unlike a conventional spherical lens, a "cylinder lens" has curvature along only one axis, as shown in the first figure. Cylinder lenses are useful in applications where light needs to be manipulated in only one direction. The example shown is a plano-convex positive lens, which brings parallel rays to a line focus.Read More >

Have you ever tried to take a picture of a bright full moon or a star-filled sky, only to be disappointed when virtually nothing shows up on your phone screen? The distance and brightness of these objects make it nearly impossible to get a sharp image—and that’s just in our own galaxy.Read More >
The annual SPIE Photonics West conference in San Francisco set new attendance records. More than 22,000 people met to discuss the latest in light-based science and engineering, and the exhibition hall, featuring 1,345 companies, sold out months in advance. The BiOS, LASE, and OPTO conferences were the place to learn about the latest photonics R&D.Read More >
Do other optics suppliers think you’re weird for wanting large lenses? We don’t.
As more and more optical suppliers consolidate and streamline their businesses, few continue to carry large diameter lenses. This is problematic because large diameter optics remain critical for precision instruments such as telescopes and imagers.Read More >
Smartphones are so ubiquitous that it is easy to forget the extraordinary technology we carry in our pockets. The 2015 generation smartphones have over twenty times the processing capability of IBM’s famous Deep Blue supercomputer, and they also feature a high-resolution camera and a wireless internet connection. With very little modification a smartphone can become a powerful, portable scientific instrument. Here are a few of the more unexpected smartphone applications.Read More >
Dr. William G. Gaines, President and COO of Thunder Energies Corporation (TEC), a company publicly traded OTCQB with stock symbol TNRG, announced last month that Ross Optical Industries of El Paso, Texas has been selected to manufacture the proprietary concave lens for the Santilli Telescope. This significant agreement was reached after months of tests and discussions between the parties.
