Schneider-Kreuznach - Short-Wave Infrared (SWIR) Filters for Industrial Applications
SWIR filters from Schneider-Kreuznach are designed to transmit short-wave infrared light while blocking visible and unwanted wavelengths, enhancing contrast and image clarity. These filters are particularly adept at revealing hidden details not visible to the naked eye, such as moisture in materials, defects in semiconductors, or underlying layers in artwork. Schneider-Kreuznach's SWIR filters feature narrow bandwidth and steep edges, allowing for precise detection and improved quality of analyses. They are used extensively in spectroscopy for chemical composition identification, in imaging and surveillance for better visibility in challenging conditions, and in quality control to identify defects and contaminants. Their applications span across medical imaging, where they improve tissue visualization, and art restoration, where they uncover hidden elements beneath the surface. These filters are robust and comply with stringent DIN environmental standards, ensuring durability and consistent performance in demanding industrial environments.
SWIR is the third dimension next to VIS and grayscale. It can make things visible that are invisible to the naked eye. For example, overpainted scenes in paintings, bruises on fruit, or empty spaces in pharmaceutical packaging. None of this would be visible without SWIR. The SWIR filters from Schneider-Kreuznach, with their narrow bandwidth and steep edges, help to detect exactly these things better and more efficiently. As a result, they help to significantly improve the quality of analyses.
What is the function of a SWIR filter?
A SWIR filter selectively transmits short-wave infrared light to reveal details not visible in the visible spectrum.
Where is SWIR filter used?
SWIR filters are used in a variety of applications, including spectroscopy to identify chemical composition, imaging and surveillance to improve visibility in challenging conditions, and quality control to detect defects and contaminants. They are also essential in medical imaging to better visualize tissue and in art restoration to reveal hidden layers beneath paintings. SWIR technology improves analysis and detection across industries by making the invisible visible.
