| Locate the scanner tube lenses, C-mount adapters, and scanners. Attach the scanners to the C-mount adapters as shown in Figure [fig:Scanner-assembly]. Attach the tube lens assemblies to the lower MIM-CUBE-II ’s using a 2 mm Allen wrench to secure the three set screws to the adapter ring. Insert the C-mount adapter with scanner attached into the tube lens fitting and secure with the set screws((On some early systems the scanner tube lenses were fixed to the frame, similar to the camera tubes. This is no longer recommended. Some hardware changes may be required to retrofit to the recommended configuration with the scanners fixed to the filter cube; contact ASI for details.)). Be sure the scanner assembly is aligned parallel / perpendicular to the MIM-CUBE-II. | Locate the scanner tube lenses, C-mount adapters, and scanners. Attach the scanners to the C-mount adapters as shown in Figure [fig:Scanner-assembly]. If needed, attach the tube lens assembly to the lower MIM-CUBE-II using a 2 mm Allen wrench to secure the three set screws to the adapter ring. Originally a 15 mm spacer was used, but a 7.5 mm spacer is generally preferred. |

| The scanners should be attached such that the fiber connectors are facing upwards and in toward the center at a 45 degree angle as shown in Figures [fig:Scanner-assembly], [fig:Andor-Zyla-cameras], and [fig:PCO-Edge-cameras]. Be sure all of the set screws on the lens tubes, cubes, and C-mounts that hold the scanners are snug and the that scanners cannot wiggle around on the mount. After firmly securing the C-mount to the scanner, tilt adjustment is made by rotating the C-mount in the lens tube and securing with the set screws for the C-mount. | <imgcaption Scanner_assembly|Scanner attached to C-mount adapter with tube lens assembly ready to be installed.>{{:docs:manual/Scanner_assembly.jpg?300|Scanner attached to C-mount adapter with tube lens assembly ready to be installed.}} </imgcaption> <imgcaption Scanner_tube_install|Tube lens assembly is attached to lower cubes on the microscope.>{{:docs:manual/Scanner_tube_install.jpg?300|Tube lens assembly is attached to lower cubes on the microscope.}}</imgcaption> <imgcaption NotToWellAligned|Scanner attached at C-mount with poor alignment>{{:docs:manual/NotWellAligned.jpg?300|Scanner attached at C-mount with poor alignment}}</imgcaption> <imgcaption BetterAligned|better alignment>{{:docs:manual/BetterAligned.jpg?300|better alignment}}</imgcaption> |

| | The scanners should be attached so the fiber connectors are facing upwards and in toward the center at a 45 degree angle as shown in the figures. In other words, the scanner assembly is aligned parallel / perpendicular to the MIM-CUBE-II. Be sure all of the set screws on the lens tubes, cubes, and C-mounts that hold the scanners are snug and the that scanners cannot wiggle around on the mount. Coarse rotation of the scanner is best done by loosening the set screws between the tube lens and C-mount adapter. Fine rotation can be done by grasping the tube lens and turning it (the threads of the lens assembly will slip some, allowing the tube body to rotate relative to the end of the tube lens near the lens. |

| With the objectives inserted and everything reassembled, get the two objectives aligned (co-focused) “by eye” as best as possible using the bushings on both sides and the lateral adjuster. When aligned, the objectives will be symmetric when viewed from the front of the microscope and aligned forward and backward as well, as shown in Figure <imgref two_objectives_closeup>. | With the objectives inserted and everything reassembled, get the two objectives aligned (co-focused) “by eye” as best as possible using the bushings on both sides and the lateral adjuster.
