Section III-D: Mounting Accessories to the SP-2300i Slit Assemblies
All Acton accessories come with their own set of instructions for proper mounting and operation. The
instructions below are only general information. Please refer to the individual instructions for detailed
information.
Accessories: The full range of Acton monochromator/spectrograph accessories mount directly to the
SP-2300i slit assemblies. To assist you in mounting accessories, a drawing of the standard slit assemblies has
been provided in Appendix V-C. The general procedure for mounting an accessory to the slit is as follows:
1. Place the accessory directly against the face of the slit body. Light sources normally mount on the
entrance slit, detectors on the exit slit. Other accessories such as fiber bundles normally mount on the
entrance slit, but are also compatible with the exit slit.
2. Using four (4) 8-32 screws normally provided with the accessory, secure the accessory to the slit body.
Light sources fitted with light collection/focusing optics are normally factory aligned to the standard slit.
Note: In some instances with light sources, there is limited access to the bottom two screw
holes. In this case, Princeton Instruments provides special slotted holes in the light source
housing to facilitate mounting of the source to the slit.
