3.4 Above-stage variant with Motorised Objective Changer (MOC)
Figure J: Above-stage variant with motorised objective changer (MOC).
The MOC (Motorised Objective Changer) variant is designed to permit users to change rapidly and
automatically between a low-power objective lens (such as X4 or X10) used for setting up a sample and
electrodes and a higher power imaging objective (such as 40X, NA 0.8 or 60X, NA 1.0 from Olympus). The
motorised objective changer is designed for use with RMS-thread objectives only.
This variant is supplied as a three-part complete assembly ā the two-photon detection module (optical block
and one or two detectors), the motorised objective changer and a mounting bracket (with a set of bolts to suit).
The assembly can be mounted to the SliceScope directly, and operated immediately
Note: The MOC variant can accommodate an Olympus-style DIC prism if required. If you wish to use
DIC, then you will need to disassemble the system to insert the appropriate DIC prism into its holder
and then re-assemble the parts. See section 3.4.2 Fitting a DIC Prism.
