Custom Optical Interference Filter For Spectral Analysis and Machine Vision

Custom Optical Interference Filter For Spectral Analysis and Machine Vision

Filter is a kind of optical element which can select the transmission, reflection, cut-off and attenuation of spectral wavelength. According to its function, it can be divided into band-pass filter, long wave pass filter, short wave pass filter, dichroic filter, neutral density filter, notch filter, cold mirror, hot mirror, color filter, etc. These filters are widely used in spectral analysis, biomedicine, machine vision, fluorescence microscopy, industrial automation and other industries and product fields. The band-pass filter selectively allows and blocks the transmission of a certain spectral wavelength within its spectral range; the neutral density filter reduces the luminous flux by reducing the transmittance of the specified spectral wavelength range, which is conducive to the protection of sensors / electronic components, and is widely used in the field of laser optics / optoelectronics; the cold / hot reflector It can reflect and transmit the light with longer wavelength in the spectrum range, which is widely used in the lighting system, which is beneficial to eliminate the heat generated in the lighting system. We not only provide filter standards, but also customize filters according to your needs.
