Filter assemblies

May 1, 1997
The NFC-446-040 Raman Notch Filter Assembly is designed to allow easy use of Raman notch and cut-off filters with the company`s SpectraPro Imaging Spectrographs. The device collects the output of fibers, collimates the beam, passes it through the notch filter, then reimages the filtered light on the entrance port of the spectrograph. The accessory accepts 1.5-in.-diameter filters and includes tilt adjustments for tuning the filter to the laser wavelength.
