A 365nm bandpass filter is a type of optical filter that allows only a narrow range of wavelengths centered around 365 nanometers (nm) to pass through while blocking other wavelengths. This type of filter is often used in scientific and industrial applications, such as fluorescence microscopy, UV curing, and water purification.

A 365nm bandpass filter is a useful tool for isolating and studying specific wavelengths of light in a variety of scientific and industrial applications.
