This paper reviews recent advances in the development of infrared zoom lenses that meet challenging requirements for reduced Size, Weight, and Power (SWaP) while enabling high-resolution vision and identification in harsh environmental conditions and constrained platforms such as airborne and portable systems. The paper also describes design considerations and performance of advanced folded-optics and lightweight zoom lenses optimized for next generation infrared thermal imaging systems and applications.
Lens coatings are an essential part of high-power CO2 laser systems. Coatings must protect the lens and allow for the highest levels of optical performance, with low levels of absorption and a long life expectancy. Transparency is another coveted characteristic for use with visible HeNe red laser pointers. The cost/benefit ratio of a coating must also be considered, as well as the environmental impact of the substrates used. For optical manufacturers, the challenge is in developing a lens coating that excels in all of these areas.
Many factors must be considered when developing a solution that requires a thermal imager or infrared (IR) camera, such as the application, waveband requirement, minimum resolution, pixel size, and the ability to scale production.
When laying out a site design for surveillance using currently marketed uncooled thermal cameras, it is important to understand the coverage capability of the cameras under evaluation in terms of field of view and range.
This application note discusses how Telops improved on the nature of gaseous studies through developing a multispectral imaging system that allows 8-channel synchronized acquisition at high frame rates.
There seems to be a never-ending list of ways light meters are used in a wide range of industries. These powerful luminance meters give technicians an accurate appraisal of the characteristics of any number of light sources and are used for quality control and other important purposes.
