Question about Nikon Coolpix 4500 Digital Camera
When I attach my Coolpix camera to a microscope I see a series of circles in the image. What are they?
Posted by Anonymous on
Under some circumstances when using the Coolpix 4500 attached to a microscope concentric rings are visible as in the below. The COOLPIX 4500 aspherical lens surface is ground to create the ideal curves to gather rays at the focal point with an extremely high accuracy. Such minute lines are not visible in the image taken with a camera alone, however if the camera is used with a microscope, the lines become visible as the depth of field is increased due to the combined F numbers of the camera lens and microscope lenses.
