Bright Ideas presents the most captivating news and innovations in photonics. This week, novel approaches are explored in freeform optics and fluorescence imaging, NASA nails down a new date for the James Webb Space Telescope launch, and Optica names its photo contest winners and honorary member award recipient.
Optical alignment and micro-optic positioning are challenging, time-consuming processes. Tiny positional variations in photonic and optical manufacturing can mean the difference between success and failure. This article discusses active alignment as a technology that improves the performance, profitability and yield in manufacturing advanced optics and photonics components for the modern era.
Hydraulic fracturing, or “fracking,” involves drilling into the ground and then directing high-pressure water at the rock to release the gas inside. While fracking has had a major impact on the energy industry, many critics have environmental concerns—particularly regarding earth tremors and potential groundwater contamination.
G&H’s expertise is founded on the use of best-in-class materials, image sensors, and control electronics. One arena that presents particularly interesting opportunities for the team to go above and beyond in accommodating customers’ special requirements is SWIR – short-wave infrared.
During the coronavirus pandemic, high-power germicidal LEDs have been used to disinfect hospital staff. The technology for use against multi-resistant bacteria has been shown to be successful with the SARS-CoV-2 virus.
At Gentec-EO, we understand that the essence of our business has been delivering accuracy for over 45 years. There are no half measures: It either measures accurately, or it doesn’t. One of our company’s values is “rigorousness,” because our customers expect nothing less.
With the goal of obtaining a photodiode that's more neutron-resistant than what's typically used in an RFS, experiments were performed in this case study to evaluate several different planar silicon photodiodes.

This paper reviews advances in the development of infrared zoom lenses that meet challenging SWaP requirements while enabling high-resolution vision and identification in harsh environmental conditions and constrained platforms such as airborne and portable systems.
SCHOTT Borofloat 33 is a floated borosilicate glass that is generally used in applications with extreme thermal and/or chemical demands with the ability to exceed the chemical durability of most metals and other materials.
Sensors Unlimited’s Multi-Mode Micro-SWIR 640CSX video camera is ideal for laboratory, factory, military, and other applications requiring SWIR imaging and detection/decoding of NIR/SWIR pulsed lasers. The camera enables rapid identification of common battlefield targeting lasers, including those with covert eye-safe laser wavelengths. Lightweight and compact, the 640CSX MMT allows its user to view images despite haze, dust, and smoke while reducing fratricide and collateral damage.
