Auxiliary lens

This element is requested to decrease magnification.

To decrease the magnification of a microscope we can act replacing eyepieces or objective lens. The choice can affect the working distance or the magnification itself whether photographic image capturing systems are used.
If the working distance is a criticity, we must proceed by replacing the eyepieces with higher magnification, otherwise when image capturing systems are present, the additional objective lens must be replaced.

The outer surface is black with two silver stripes to indicate the possibility to clasp a ring light source. The frame is metal to be coupled with XTS/XTD/XTG optics by threaded coupling.
