In the past, a thin-film design software was used to help develop the coating, but the real challenge was in actually replicating the design thickness and the material indexes inside the coating chamber, without any errors.
Most of the optical materials used for components that operate in the visible range — glasses and coating materials — are also transparent in the SWIR range. This article provides information on the benefits of SWIR imaging in harsh or low-light level conditions and outlines the capabilities for manufacturing optical components for SWIR imaging.
Optical products, traditionally used for visible light tasks, are moving aside to make room for more specialized optical components that are being manufactured for use in ultraviolet and infrared systems. Selecting and working with the finest infrared materials is essential to delivering high-performance results.
Specialized thin film optical coatings are currently being designed into customized displays that serve to modify the viewing angle and eliminate unwanted stray light that would otherwise distract the pilots and crew in commercial and military aircraft cockpits.
Precision Glass & Optics (PG&O) introduces finished infrared optics for a range of applications, including biomedical, industrial, military/defense, homeland security, surveillance systems, automotive, fire control, lasers, night vision, and more.
