At Z-Optics, our SHORTPASS FILTERS are precision-engineered optical filters designed to transmit wavelengths shorter than a specified cut-off point while effectively blocking longer wavelengths. These filters provide excellent optical density (OD) and broad operational wavelength ranges, making them indispensable components in diverse optical and photonics systems requiring sharp spectral cutoff.

Key Features

  • Precise Cut-Off Wavelengths: Available across a range of cut-off wavelengths from 395 nm up to 950 nm, tailored for diverse UV, Visible, and NIR applications.
  • High Optical Density (OD): Optical blocking strength of OD3 to OD5 ensures minimal transmission of unwanted wavelengths, enhancing signal clarity and contrast.
  • Broad Wavelength Operation: Supports extended wavelength ranges from 200 nm up to 1100 nm depending on the model, allowing flexible integration in various optical setups.
  • Standard Diameters: Available in 12.7 mm and 25.4 mm diameters, compatible with most optical mounts and instrumentation.
  • Durable Coatings: Advanced multilayer dielectric coatings offer long-term stability, high laser damage thresholds, and resistance to environmental factors.
  • Customizable Options: Filters can be customized for specific cut-off wavelengths, diameter sizes, and operational ranges to suit unique application needs.

Applications

  • Spectroscopy systems requiring sharp wavelength cutoff for signal isolation.
  • Fluorescence microscopy and biomedical imaging to separate excitation and emission bands.
  • Laser safety and beam shaping in industrial and scientific laser systems.
  • Optical sensing and environmental monitoring devices where wavelength selection is critical.
  • Machine vision and quality control inspection systems operating under variable lighting.
  • Multispectral and hyperspectral imaging to enhance spectral discrimination.
