Notch Filters SKU: 246-2506-488

Notch filters, or stop-band filters, are designed to block a specific narrow wavelength range (stop band) and to transmit broad wavelength ranges outside of this band (pass bands). These optical filters feature high optical density (OD), which is a logarithmic measurement of the…
