A 260nm bandpass optical filters is an optical filter that allows only light with wavelengths around 260nm to pass through, while blocking other wavelengths. This type of filter is commonly used in scientific and industrial applications, particularly in the fields of ultraviolet (UV) spectroscopy and imaging.
