Schneider-Kreuznach SWIR Filters: Making the Invisible Visible for more precise Material Analysis

Schneider-Kreuznach's SWIR (Short-Wave Infrared) filters, with their narrow bandwidth and steep edges, transmit only this spectral range required for high-precision data acquisition and the revelation of invisible details. This technology is indispensable in quality control, image processing and numerous other applications - from spectroscopy and medical imaging to art restoration.

The latest generation of SWIR filters from Schneider-Kreuznach opens up completely new possibilities for industry and science. These specially developed filters transmit small band short-wave infrared light and blocks unwanted environmental light, revealing details that otherwise remain unseen. They are ideal for detecting hidden defects and optimizing material analysis.

A look behind the scenes - SWIR filters in use
- In quality control, they help detect defects and contaminants that are invisible to the human eye.
- In spectroscopy, they enable the precise determination of the chemical composition of materials.
- In medical imaging, they help make tissue structures visible.
- In art restoration, they are used to reveal hidden layers in paintings.
Without this technology, for example, it would not be possible to detect overpainted scenes in works of art or bruises on fruit. Cavities in medical packaging can also be made visible with SWIR.

Technical Highlights of SWIR Filters
- Average transmission of 80-90%: High light throughput for optimal results.
- Steep edges: Isolate specific wavelengths for maximum precision.
- Wavelength tolerance of +/- 5 nm: Precise and accurate filtering.
- High Optical Density: Effectively blocks unwanted environmental light.
With these technical advantages, Schneider-Kreuznach SWIR filters make a decisive contribution to improving analyses in many industries.
