To provide even illumination of a large field use a lamp with a large filament. This is especially important for the 2X lens. A 24 volt, 300 watt, tungsten-filament lamp has a relatively large filament.
While the photograph of the MacroScope on the web site shows the MacroScope to be free standing (separate from a camera), we find it more convenient to attach the MacroScope directly to the camera via the vertical C-mount. This fixes the alignment and the distance between the lens and camera. RedShirtImaging provides mounting hardware for NeuroPDA or NeuroCCD cameras with the MacroScope.
The MacroScope is designed to form a real inverted image 1.7 cm above (past) the end of either C-mount. For both the 2X and the 5X objectives a working distance of about 1.0 cm should form an image at the correct location.
