C-Mount
For a camera equipped with a C-mount thread, use a standard C-mount adapter supplied
by the microscope manufacturer to attach the camera to the microscope. If you don’t have
an adapter, you can obtain one through your microscope distributor or you obtain dealer
information from Diagnostic Instruments at its website at www.diaginc.com.
The adapter can be screwed into the camera and then the assembly can be secured to the
microscope using the standard setscrews on the microscope. The camera can be mounted
on the trinocular output port, the side port or the bottom port of the inverted microscope.
When mounting the camera perpendicular to the microscope on the side port, we
recommend that you provide some additional support for your camera to reduce the
possibility of vibrations or excessive stress on the C-mount nose. For the bottom port of
the inverted microscope, the C-mount is designed to support the full weight of the
camera, however, you may wish to provide some additional support for the camera since
the detector is in a position where it could be deflected by the operator’s knee or foot.
This kind of lateral force could damage the alignment of the nose and result in sub-
optimal imaging conditions.
Most output ports of the microscope do not require additional optical elements to collect
an image, however, please check with your microscope manual to determine if the chosen
output port requires any relay lens. In addition, all optical surfaces should be free from
dust and finger prints, since these will appear as blurry regions or spots and hence
degrade the image quality.
Operation
Xenon or Mercury Arc Lamp Precautions
Before You Start, if your system includes a microscope Xenon or Hg arc lamp, it is
CRITICAL to turn off all electronics adjacent to the arc lamp, especially your digital
camera system and your computer hardware (monitors also), before turning on the lamp
power.
Powering up your microscope Xenon or Hg lamp causes a large EMF spike to be
generated that can cause damage to electronics that are running in the vicinity of the
lamp. We advise that you place a clear warning sign on the power button for your arc
lamp reminding all workers to follow this procedure. While Roper Scientific has taken
great care to isolate its sensitive circuitry from EMF sources, we cannot guarantee that
this protection will be sufficient for all EMF bursts.
Focusing the Microscope
1. Direct all of the light to the eyepieces
2. Focus on the target, set up Koehler illumination and adjust the condenser to
match the objective, all in the transmitted light mode (as per the instructions
provided by your microscope manufacturer).
3. Decrease the transmitted light intensity to a level that is low, but still sufficient to
allow visualization by eye.
4. Redirect the light to the camera port.
