Filters for Specific Applications

Photolithographic and astronomic filters are available in this section. The different optical filters available are as versatile as the applications are varied.

Notch Filters

Notch filters have a high attenuation within a narrow wavelength range.

Filters for Specific Applications

Notch filters are band blocking filters and are traditionally intended for suppression of powerful laser beams in research experiments, such as Raman laser spectroscopy and other applications. They can also be used for eye protection and as a camera accessory.

 

Optical Specifications

  • Blocking: OD 4 or 6 at Notch wavelength
  • Transmission: >90%
  • CWL: Notch wavelength
  • 50% bandwidth: deptending on type (approx. 10-70 nm)

Physical Specifications

  • Free aperture: >8 mm or >20 mm
  • Outer diameter: 12.5 mm or 25 mm +0.0/-0.2 mm
  • Ring thickness: ≤ 5.0 mm

Other sizes such as, for example, 50 mm or larger can also be produced upon request!
Furthermore, we can also offer other wavelengths than the well-known standard notch wavelengths.
