Longpass Filter is a transparent optical element designed to transmit light of longer wavelengths in selection than the cut-on wavelength while blocking or attenuating shorter wavelengths. The fundamental function of a long pass filter is to allow light beyond a specific wavelength, known as the "cuton wavelength," to pass through while obstructing shorter wavelengths. For example, an IR longpass filter permits infrared light to pass while blocking visible and ultraviolet light. This is achieved through utilizing specialized coatings or materials that are capable of the discrimination of the designated wavelengths. Long pass filters provide flexible control over the light spectrum, enhancing image qualities and facilitating various optical processes. The wide transmission range and versatile functions of longpass filters make them essential components in a wide range of optical applications, such as photography, spectroscopes, microscopes, and sensor technologies.
