A long pass filter is an optical filter designed to transmit light with wavelengths longer than a specific cutoff value while blocking or attenuating shorter wavelengths. These filters are often used in applications that require selective wavelength control, such as fluorescence microscopy, spectroscopy, photography, and machine vision.
