Air purifying respirators use cartridges or canisters constructed of carbon or paper-based filters to remove contaminants or particles from non-IDLH (Immediately Dangerous to Life and Health) environments. Air purifying respirators that rely on the user's inhalation to draw the ambient air over the filters are called negative pressure air purifying respirators. Those that utilize blower to pull the ambient air through the filters and then push it to the user are called positive pressure air purifying respirators. Air-purifying respirators have numerous applications from construction and automotive repair to pharmaceutical and oil production.
207-000 6-18mm f/2.8 3:1 Miniature Zoom Lens
Smallest optical zoom lens with focus tracking available in the market place. High resolution images suitable for broadcast and machine vision applications.
Samples are immediately available. Lenses have M12 X 0.5P thread mount and can be easily repackaged to meet customer needs. Westech can always design a lens to meet exact requirements including glass - plastic hybrids. We have in-depth experience with high volume-high performance optics and can provide stock and custom lenses - quickly and inexpensively.
Typical requirement for lenses and optical systems in civilian and military security and surveillance applications are for compactness, high performance and versatility. The Resolve Optics team has worked with a growing number of security focused organisations to provide novel, high performance solutions including miniature surveillance lenses, CCTV lenses and optics for ultra-high speed imaging systems, night vision systems and thermal imagers.
Resolve Optics has developed a comprehensive range of non-browning (radiation resistant) lenses for use in radioactive environments. All our lenses are manufactured to the highest standards of quality and performance and are designed to withstand a total radiation dose of 108 rads.
In keeping with Resolve Optics tradition of designing unique lenses we are able to provide NB lenses to meet your exact specification. If you can not find a lens, within our standard range that meets your requirements, please contact us to discuss the possibility of developing a lens for you.
