LBTEK Laser Line Bandpass Filters are manufactured by vacuum deposition of optical thin-film materials on substrates. A filter typically consists of multiple dielectric layers with different refractive indices stacked together, forming Fabry-Perot (F-P) interference cavities between the dielectric layers and intermediate spacer layers. The thickness of the dielectric layers is λ/4, while the thickness of the intermediate spacer layer (F-P cavity) = (nλ)/2 (where λ is the design center wavelength and n is an integer), satisfying constructive interference at the center wavelength. As a result, only the center wavelength can fully transmit through. By adjusting the thickness of the spacer layer and the number of dielectric layers, the center wavelength and bandwidth of the filter can be modified. In addition to standard line filters, LBTEK also offers customized filter services. For special requirements, please contact LBTEK Technical Support.

  • Center Wavelength: 532 nm
  • FWHM: 3±0.6 nm
  • Transmittance (@532 nm): >60%
  • Stopband Range: 200 nm-1200 nm

LBTEK filters are mounted in black anodized aluminum rings, with the incident direction marked by an arrow on the housing for easy installation and use.  In order to prevent the substrate coated with the cutoff material from being subjected to radiation outside the passband wavelength, which may cause thermal effects and reduce the filter characteristics, it is recommended that the side coated with the cutoff film face the light source (light propagates in the direction of the arrow). The filter's dielectric coating thickness is designed based on collimated light incident perpendicularly. If the light is not collimated or incident perpendicularly on the filter surface, the designed center wavelength will shift to a shorter wavelength, and the bandpass transmittance curve will change. All LBTEK circular lenses can be mounted in LBTEK standard lens tubes, fixed lens mounts, and various coaxial mounting plates. Customers can select the optimal mounting method for different application scenarios.

LBTEK coaxial mounting plate can be used to install laser line filters.
