Longpass filter
Longpass filters are used to transmit light longer than the cutoff wavelength and shield light shorter than the cutoff wavelength by absorption or reflection. Long-pass filters have many applications, and combined with short-pass filters, they can realize the function of adjustable band-pass filters.Longpass filters are designed to have a sharp transition from reflection to transmission, making them ideal for various applications.
