Specific Magnification with the Greatest Working Distance

Infinity instruments and lenses are able to be amplified. This means that additional optical elements can be introduced to increase magnification. Since most Infinity instruments and lenses have internal focusing (by patented AVS™, InFocus™ or DFS™ systems), magnification can be increased by introducing an amplifier. Once done, the instrument or lens can be moved further away from the object—yet the original magnification can be retained. This also tends to increase depth of field.

For example:

If you plan to use an InfiniTube, Model KC/S, or Model K2/S with a supplemental objective, use a lower-powered one. Then, by using a DL Tube 2x amplifier between imager and video camera magnification can be increased—yet the longest possible working distance can be maintained.

This same technique can be used with Model K2/S and a TR or TX Tube 2x amplifier for all formats—even direct 35mm (43mm diagonal) format cameras. Rest assured that there is not a single Infinity instrument or lens that cannot be amplified. If you need help to determine the best way, please contact us.
