Optical Filter

Optical filters are optical components designed to selectively transmit, block, or attenuate specific wavelengths of light. They are typically made from optical glass or other optical substrates, with the desired spectral characteristics achieved through bulk coloration or precision optical coatings. By controlling parameters such as transmission range, cut-off wavelength, bandwidth, and transmittance, optical filters provide precise wavelength selection and control.
We offer a wide range of optical filters, including bandpass, shortpass, longpass, UV & IR cut, narrow bandpass, color, and neutral density filters. Custom solutions are also available to meet specific requirements for wavelength range, dimensions, and spectral performance. Our filters are widely used in machine vision, spectroscopy, biomedical imaging, fluorescence detection, laser systems, and optical instruments.
