280nm UV bandpass filter is a type of optical filter that selectively transmits light within a narrow wavelength range centered around 280 nanometers (nm) while blocking light at other wavelengths.

The 280nm bandpass filter is an important tool for researchers and scientists working in a range of fields, allowing them to isolate and analyze specific regions of the electromagnetic spectrum with high precision and accuracy. It is commonly used in scientific and industrial applications such as fluorescence microscopy, UV spectroscopy, and UV curing.
