Collection: UV Bandpass Filter (100-400nm)

1. Forensic Analysis
In forensic science, UV bandpass filters are used to enhance the visibility of certain substances. For example, they can isolate UV-induced fluorescence from biological samples or trace evidence, allowing forensic experts to identify and analyze materials that might otherwise be invisible under normal lighting conditions.
2. Phototherapy
In medical applications, particularly in phototherapy for skin conditions like psoriasis or eczema, UV bandpass filters are employed to transmit specific UV wavelengths (typically UV-B) that promote healing while minimizing exposure to harmful wavelengths.
3. Sterilization Processes
UV-C bandpass filters are crucial in sterilization applications, especially around the 254 nm wavelength, which is effective for killing bacteria and viruses. These filters ensure that only the sterilizing UV light passes through, enhancing the efficacy of UV sterilization systems used in healthcare settings or water treatment facilities.
4. Environmental Monitoring
In environmental science, UV bandpass filters are utilized in instruments designed to monitor gaseous pollutants. For instance, they can selectively measure specific gases like sulfur dioxide (SO₂) that have distinct absorption characteristics in the UV range, providing accurate data on air quality.
5. Fluorescence Microscopy
In research settings, fluorescence microscopy often employs narrowband UV filters to isolate specific wavelengths emitted from fluorescent dyes. This allows researchers to visualize cellular components with high specificity and contrast, facilitating detailed studies in biology and materials science.
6. Solar Research
UV bandpass filters are also used in solar research to study the sun's ultraviolet emissions. By filtering out unwanted wavelengths, scientists can focus on the UV spectrum to analyze solar activity and its effects on Earth's atmosphere.
