Optical Filters is a kind of optical component that has a targeted selection of spectral wavelength transmission, reflection, cutoff, and attenuation. According to its function, it can be divided into band pass filter, long pass filter, short pass filter, and A color filter, a neutral density sheet (ND Filter), a notch filter, a cold mirror, a heat mirror, a color filter, and the like. These filters are widely used in industries such as spectroscopic analysis, biomedical, machine vision, fluorescence microscopy, industrial automation, and other products. The bandpass filter selectively allows a certain spectral wavelength to pass through and block the transmission of a certain spectral wavelength in its spectral range; the neutral density filter (ND Filter) reduces the transmittance of a specified spectral wavelength range, thereby Reducing the luminous flux, which is beneficial to the protection of sensors/electronic components. It is widely used in the field of laser optics/optoelectronics; cold/heat mirrors can be used for targeted reflection and transmission of longer wavelengths in the spectral range. Application in the lighting system helps to eliminate the heat generated in the lighting system. MAP optics can customize filters for your needs.
