SWIR lenses, or short-wave infrared lenses, are lenses specifically designed for between 900 and 1700 nm, the short wave infrared region. At Shanghai Optics we manufacture high quality SWIR lenses for various applications, including biomedical imaging, security, anti-counterfeiting imaging and solar cell inspection.
In industry, SWIR imaging is used for quality control and machine vision, as it is unaffected by the presence or absence of visible light and allows for imaging through nontransparent substrates such as silicon. Detecting bruising on fruit without the need for any invasive testing or external illumination is just one of the many applications of SWIR lenses.
We carry a range of high resolution manual focus SWIR lenses in stock, with focal lengths ranging from 12mm to 100mm. They match InGaAs FPA formats, and both C-Mount and Bayonet interfaces are available. Standard SWIR lens sizes include 16mm, 25mm, 35mm, and 50mm.
Our lenses provide a large field of view and low distortion (less than 2%). Our 50mm and 100mm focal length options are designed to work with 1024×768-17µm sensors, enabling ultra-high resolution imaging and crystal-clear inspection shots. These high-performance lenses are ideal for machine vision applications where an accurate and detailed view is crucial.
If our in-stock options do not meet your needs, our experienced IR optics team can work with you to produce custom SWIR lenses. Our in-house factory and over 55 years of experience in the industry enable us to fully meet your desired specifications. Our experts would be happy to work with you and provide any design assistance you might need.
SWIR lenses are widely recognized for their role in outdoor night vision cameras (SWIR cameras), making them crucial in defense and civilian security applications.
However, their utility extends beyond security. In medicine, SWIR lenses are vital for biomedical imaging. They also contribute significantly to environmental stewardship and various industries. For example, the fruit industry uses SWIR imagery to differentiate between blemished and good fruit. Bruises or soft spots invisible in visible light are clearly distinguishable with SWIR technology.
Every SWIR lens we produce is carefully tested for quality before leaving our factory. State-of-the-art testing equipment ensures that each optical piece performs consistently and reliably in its intended application. Rated according to ISO and Mil standards, our lenses come with our commitment to provide technical support both before and after installation.
