Spectral Shaping and Response Flattening Filters

Shaping filters of any spectral profile can be achieved in the UV, Visible, and NIR regions. These filters improve many applications where a skewed response due to unbalanced detector sensitivity and/or wavelength dependent source intensity place an extreme demand on the system's gain.

Any desired spectral shape with regions of varying attenuation and transmission is possible.

  • Standard Sizes: 12.5, 25 and 50 mm
  • Size Tolerance: +/- 0.25 mm
  • Custom sizes are available

Application: Balancing the spectral response of detectors and sources.
