Customized Filters for Spectral Analysis I

Notch filters

Notch filters, or band stop filters, reflect and remove the specific narrow wavelength band only and pass the other wavelength range. Our notch filters have not only narrow rejection band and wide pass band, but also small polarization dependence at incident angle of 45 degrees. We will design the filters in accordance with your demands and will propose the best solution for the center wavelength and bandwidth of rejection band, pass bandwidth, and so on.
