NF633-25 Bandstop Negative Notch Filter

The depth super series of Ruicheng photoelectric notch waveplates, with strict wavelength control, excellent steepness, and wide transmission range, can accurately block lasers or other light sources without sacrificing the quality of the target wavelength band.

The design and testing of the Super Series notch filter exceed the requirements of state-of-the-art instruments. It has good application value in fluorescence microscopy, gastroscopy examination, and DNA sequencing.

Super series notch filters can also be customized to cut off the steepness of Raman spectroscopy applications. In some Raman applications, band stop notch wavesoptical filterUsed to block the excitation laser wavelength while transmitting Stokes and reverse signals to the detector. If the edge of the notch is not steep, the signal close to the laser wavelength will be lost.

Applications: Flow cytometry, Raman spectroscopy, fluorescence microscopy imaging, etc.
