Supplemental Instructions Model NFC-446-040 Raman Notch Filter Assembly Description: The ARC Model NFC-446-040 is a filter chamber designed to permit use of Raman notch filters with ARC monochromators and spectrographs. It is designed primarily to collect the output of fiber optics, however it may be used with other sources of Raman scatter (e.g., focused sample image or direct collection of scatter from a sample positioned close to the NFC-446040).
Figure 1: NFC-446-040 Layout (Top View) Mounting the NFC-446-040 to Acton Series Monochromators or Spectrographs: Use the illustration above for reference when mounting the NFC-446-040 to ARC monochromators or spectrographs. 1. Unpack the NFC-446-040 Raman Notch Filter Chamber. 2. Remove the cover of the NFC-446-040. 3. Set the components on a stable, flat working surface.
Mounting a Filter inside the NFC-446-040: The standard filter holder inside the NFC-446-040 accepts 1.5” (38.1mm) diameter filters. Use the following procedure to mount filters: 1. If not already completed, mount the NFC-446-040 to the monochromator or spectrograph. 2. Remove the NFC-446-040 access cover. 3. Locate the filter holder between the lenses. 4. Slide the notch filter into the holder and secure it in position with the set-screw (located on top of the holder). 5. Replace the access cover.
Lens Focus: The NFC-446-040 is optimized for best performance when the light source image is in sharp focus on the monochromator or spectrograph entrance slit, and both lenses are set to the same focus position. This can be accomplished using the following procedure: 1. Assure that the NFC-446-040 is correctly mounted to the monochromator or spectrograph. 2. Mount the detection system to the monochromator or spectrograph. Assure that the detection system is operating. 3.
