SWIR Lenses
Shortwave Infrared (SWIR) wavelength band offers unique imaging advantages over visible and other thermal bands. It is quietly earning a growing place in industrial machine vision for electronic board inspection, material/food sorting, solar cell inspection, quality inspection, and in security applications. SWIR lenses are utilized where other detectors or cameras are not sensitive enough for finite detail recognition.

SWIR Lenses FAQ
A SWIR (Short-Wave Infrared) lens is specifically designed to focus light in the 0.9–2.5 µm wavelength range, which is beyond the visible spectrum. Unlike standard lenses made for visible light, SWIR lenses use specialized materials and coatings to ensure high transmission and image quality in the SWIR range.
SWIR lenses are utilized in various fields, including:
- Machine vision and industrial inspection
- Food quality control
- Semiconductor inspection
- Surveillance and security imaging
- Agricultural monitoring
- Biomedical imaging
Their ability to capture images in low-light or obscured conditions makes them invaluable in these applications.
While some standard lenses may transmit parts of the SWIR spectrum, they are not optimized for it. Using lenses specifically designed for SWIR ensures better image quality, reduced aberrations, and higher transmission efficiency in the desired wavelength range.
SWIR lenses are typically made from glass materials that have high transmission in the SWIR range, such as:
- Fused silica
- Silicon
- Calcium fluoride (CaF₂)
- Sapphire
- Chalcogenide glasses
These materials are chosen for their optical properties and durability.
AR coatings minimize reflections and maximize transmission through the lens surfaces. In SWIR lenses, specialized AR coatings are applied to ensure optimal performance in the 0.9–2.5 µm range, enhancing image contrast and reducing stray light.
Compatibility depends on factors like sensor size, mount type, and spectral response. Wavelength Opto-Electronic’s SWIR lenses are designed to be compatible with a range of SWIR cameras, but it’s essential to verify specifications to ensure optimal performance.
Wavelength Opto-Electronic offers SWIR lenses in various focal lengths, including 12 mm, 25 mm, 50 mm, 75 mm, 100 mm, and 200 mm. The choice of focal length depends on the desired field of view and application requirements.
Yes, many SWIR lenses come with manual focus and adjustable aperture (F/#) settings, allowing users to fine-tune the lens for specific imaging conditions and depth-of-field requirements.
