A UV-blocking filter is an optical filter that blocks ultraviolet light and passes only visible light to reduce unwanted UV radiation, while an IR-blocking filter blocks infrared light and
passes only visible light to minimize unwanted infrared radiation, improving image quality in optical applications such as cameras or optical sensors.

Custom Optical Filters for maximum Flexibility
We design and manufacture both the mechanics and the coatings of our filters at Schneider-Kreuznach. This enables us to produce customized optical filters that meet your exact requirements and guarantee the highest quality standards.
Improve the performance and accuracy of your machines by using our optical filters. Reduce annoying reflections, minimize unwanted wavelengths, and increase the efficiency of your processes. Our filters are the key to the smooth and efficient operation of your industrial systems. They are durable and robust, ensuring long-term use.
Highest Quality and Reliability: our Filters put to the Test
Quality and reliability are top priorities at Schneider-Kreuznach. Our filters undergo rigorous quality control to ensure maximum reliability. We use only high quality glass from reputable manufacturers to achieve very low manufacturing tolerances. As a result, our filters are of consistently high quality. Their use allows you to accurately reproduce results, as the filters will perform nearly identically even after years of use.
Our industrial optical filters are rigorously tested to DIN and ISO standards to ensure they meet stringent environmental requirements. These tests evaluate their temperature stability and ability to withstand exposure to harsh chemicals and other environmental stressors. As a result, our filters excel in demanding industrial applications, providing consistent performance and reliability over time.
Precision down to the last detail: Our high vertical integration
We are proud of our technical expertise, which we consistently apply to the production of our lenses and optical filters through our high level of vertical integration at our Bad Kreuznach site. Each of the Schneider-Kreuznach products is manufactured with the utmost care and precision to provide you with the best possible performance and reliability.
We demand the highest standards of materials and manufacturing processes to ensure excellent image quality, starting with the production of the optics. Our standards go beyond the production of individual components. We master the entire production process from raw glass to finished filters and are able to process all common types of glass. Our special coating technologies give the optics or lenses the desired optical properties.
We do mechanical manufacturing in-house. We use the latest technologies and machinery to develop robust and durable filters. With our high-end 5-axis CNC milling machines, we have world-class machining capabilities that give us exceptional precision and flexibility. These powerful milling machines allow us to realize complex geometries and sophisticated contours in the mechanical components of our filters while maintaining high reproducibility. Electroplating is performed in-house under strict environmental conditions, allowing us to customize the surface coatings of our products to meet the specific requirements of our customers.
Our lenses are assembled in dedicated clean rooms that provide a clean and controlled environment and ensure they are free of contaminants. Our qualified staff with many years of experience and expertise perform precise adjustments and calibrate the optics to the highest quality with the lowest tolerances.
Testing and Quality Assurance
Our test technology and quality assurance reflect our high quality standards. We use state-of-the-art technologies such as interferometers and 3D coordinate measurement technology to test the lenses we manufacture to ensure they meet the highest standards. Our ISO 9001 certified processes, metrology rooms and procedures ensure consistent and reliable production to meet our customers' high expectations.
