Shaping filters of any spectral profile can be achieved in the UV, Visible, and NIR regions.

Applications: 

  • flattening the spectral response of light sources that include several lamps of varying intensities

  • flattening the spectral response of a detector

  • emulating the absorption spectrum of a solution to use as a calibration standard

  • correcting spectral output of a lamp to match the solar irradiance (solar simulator)

  • Photopic Response Filters simulate the spectral sensitivity of human visual perception. These refractory oxide photopic eye response filters pass the wavelength of light in proportion to the eyes' response. The transmission of these filters, when combined with a broadband source and detector, is very similar to the spectral response of the human eye. Click here for Omega's standard photopic filters

Examples:

Source Gain Flattening: UV - VIS

Raw spectral response, corrective filter response, combined response. Note the combined response largely eliminates the dip at 350 nm.

 

Solar Simulation

Raw lamp response, filter response and combined response. The combined response closely mimics AM1 solar insolation

Multiple LED Flattening: VIS - NIR

Raw response of a light source comprised of several LEDs, filter response and combined response. The filter reduces the ripple between LED spectral peaks.
