OD 6 Notch Filters

Featuring deep blocking and broad transmission bands, TECHSPEC OD 6 Notch Filters are fabricated utilizing hard-sputtered Advanced Plasma Reactive Sputtering (APRS) Technology, guaranteeing durable coatings that will not degrade with time, temperature, or humidity. Each notch filter is mounted in a black anodized ring which has been engraved to ease filter handling, identification, and orientation. TECHSPEC OD 6 Notch Filters are ideal for applications requiring deep blocking of a narrow range, and broad transmission of other wavelengths.

Applications for TECHSPEC OD 6 Notch Filters include laser wavelength analysis where specific wavelengths need to be blocked in order to maximize system performance. For instance, in Raman spectrometers, eliminating unwanted noise from the pump laser source is critical in obtaining the optimum signal-to-noise ratio. This is easily achieved by introducing a notch filter into the instrument’s detection path.

TECHSPEC OD 6 Notch Filters feature high OD 6 blocking, one of the highest optical densities for notch filters in the optics industry. High blocking at the center wavelength coupled with high transmission of wavelengths outside of this makes these notch filters ideal when high throughput is critical.
