Visible Bandpass Filters

JNS Glass & Coatings manufactures and supplies high-performance visible bandpass filters engineered to transmit a precise range of wavelengths within the 400–700 nm visible spectrum while blocking unwanted light. Whether you need narrowband or broadband solutions, our filters deliver the spectral accuracy your application demands. These visible filters are one part of our complete line of optical bandpass filters, engineered for applications across the full spectrum.

Precision Wavelength Control for Demanding Applications

Our visible bandpass filters are designed for use in machine vision, fluorescence microscopy, spectroscopy, laser line isolation, colorimetry, and biomedical imaging. Thin-film interference coatings ensure steep edge slopes, high in-band transmission, and deep out-of-band rejection, critical for reliable, repeatable results.

Custom & Standard Configurations Available

JNS offers both catalog and fully custom visible bandpass filters, including:

  • Center wavelengths across the full visible range
  • Narrow bandwidths (FWHM) from <5 nm to broadband
  • Round, rectangular, and custom geometries
  • Hard coatings on glass substrates for durability
