Bandpass Filters (Narrow / Broad)

Only pass target wavelengths and block all other light.
  • Narrow bandpass (FWHM ≤10nm): Laser filtering, biochemistry testing, Raman spectroscopy, fluorescence microscope filter cube inserts
  • Broad bandpass (FWHM＞50nm): Machine vision, spectral separation, common lighting
  • Shortwave bandpass: Laser monochrome tuning, biological fluorescence excitation for confocal & fluorescence microscopes

Fluorescence Filter Cubes & Matching Filter Kits

Complete matched optical sets with excitation filter, dichroic mirror and emission filter.

All built-in narrow bandpass filters have high OD blocking. Fit for fluorescence microscopy, cell imaging and biochemical analyzers.

Notch Filters (Band-Stop Filters)

Low loss transmission for most light, strong suppression on specific wavelength bands.

Fit for Raman laser gear, medical analysis gear, laser protection and astronomical optics.

Filter Chart
Optical filters are precision optical components designed to select specific wavelength bands by light interference, diffraction, absorption and reflection.

Optical Filter Core Advantages & Coating Tech

Optical filters are high-precision optical parts that pick out target wavelengths via interference, diffraction, absorption and reflection.
We use advanced IBS ion beam sputtering interference coating, different from conventional dyed glass absorption coatings. Custom coating layers and substrates ensure smooth transmission curves and steady optical performance.

Our hard-coated filters meet MIL-C-48497A standards in adhesion, wear resistance and temperature & humidity stability, ideal for precision optical equipment and OEM assembly.

IBS Ion Beam Sputtering Coating Technology

This process uses high-energy ion beams to sputter target materials and form even multilayer films on glass substrates.

We adjust ion energy, incidence angle and target materials freely to customize wavelength and bandwidth.

  • Compact hard coating, minimal wavelength shift, easy to clean
  • Great heat and corrosion resistance, supports double-sided coating
  • Stable optical effect matching imported filters, more cost-efficient alternative
