In the world of light, every wavelength holds unique energy and potential. With its distinctive physical and chemical properties, 254 nm ultraviolet light plays an irreplaceable role in multiple key fields. In the medical and health sector, it acts as a highly efficient "sterilization guard," capable of destroying the DNA and RNA structures of bacteria and viruses to achieve rapid and thorough disinfection, thus building a safety barrier for places like hospital wards and laboratories. Additionally, in environmental monitoring, it can be used to detect organic pollutants in water, providing crucial data support for water purification.   A filter is like a "light filter" that selectively transmits light of specific wavelengths while blocking other unnecessary stray light. In scientific research experiments, filters ensure the purity of the light source used in experiments, making the detection data more accurate and reliable. The 254 nm ultraviolet filter only allows ultraviolet light with a central wavelength of 254 nm to pass through, blocking visible light and near-infrared light outside the passband. This helps improve the signal-to-noise ratio of sensors and ensures the sensitivity and accuracy of signal detection.   To produce high-performance ultraviolet filters, we adopt advanced coating technology, high-performance quartz substrates, ultra-high-purity coating materials, and exquisite production processes. We have mass-produced high-performance 254 nm filters with a central wavelength transmittance of 28%. The cut-off range covers ultraviolet, visible, and near-infrared bands, and their performance reaches the industry-leading level.   Product application fields: Medical blood test detectors, liquid detection, environmental detection, biological detectors, ambient air detectors, DNA detection, biochemical analysis, ultraviolet cameras, spectral analysis, light source color filtering, ultraviolet light detection, etc. The specific technical parameters are as follows:
