What to do if the image cannot be seen or is dark on my VWR VisiScope 100D?

If the image seen through your VWR Microscope is either not visible or appears dark, consider these potential causes: * The iris diaphragm aperture might not be fully open. Ensure it is completely open. * The brightness level may be set too low. Adjust it by rotating the brightness adjustment potentiometer. * The objective might not be properly aligned with the optical axis. Rotate the nosepiece until an objective securely clicks into the optical path.
