  • Available Dimensions

    Shortpass filters are dicing from a bigger coating wafer. The original wafer size is usually 60x60mm.
    (We can provide you any size under 60x60mm)

Transmission Characteristics

  • Cut-off Wavelength: The wavelength at which the filter transitions from transmitting to blocking light.
  • Transmission Band: Typically >90% transmission in the pass region.
  • Edge Steepness: Indicates how quickly the filter transitions from transmission to blocking, usually expressed as a percentage or in nanometers.

Blocking Characteristics

  • Optical Density (OD): Measures the blocking efficiency in the rejection region, typically OD > 5.
  • Rejection Region: The range of wavelengths effectively blocked by the filter.

Physical Properties

  • Diameter: dia12.5mm to dia60mm.
  • Thickness: Usually around 3.5 mm for the mounted filter.
  • Substrate Material: Often UV fused silica or optical quality glass.

Performance Metrics

  • Transmitted Wavefront Error: Typically λ/4 at 632.8 nm.
  • Surface Quality: 40-20 or 60-40 scratch-dig.
  • Angle of Incidence: Usually designed for normal incidence (0° ± 2°).

Additional Features

  • Durability: Often hard-coated for increased longevity and easier cleaning.
  • Recommended Transmission Direction: Usually indicated by an arrow on the filter edge.
