Edge Filters
Edge filter is categorized into long pass and short pass filters. A long pass filter transmits light greater than the cut-on wavelength and blocks shorter wavelengths. Short pass filter transmits light less than the cut-off wavelengths and blocks larger wavelengths. A long pass and short pass filter can be combined to customize bandpass filters. Edge filters are used to separate spectral regions such as in microscopy, industrial, or life science applications.
