Leitz ORTHOPLAN

This is another of my very high quality instruments, a LEITZ Orthoplan, which replaced the LEITZ Ortholux in the mid 1960s and was on the market until the mid 1990s. Later, in the early 1970s, LEITZ introduced a new version of the previous Ortholux, the Ortholux II, which remained in vogue until the mid 1980s. Before 1976, Leitz used the mechanical tube length (TL) of 170 mm for its biological research microscopes (both in diascopic and transmitted light illumination). Of course, the Ortholux, Ortholux II and Orthoplan can also be used as metallographic microscopes. In this case, a mechanical tube length of 170 mm is no longer an acceptable choice. Leitz objectives, designed for a tube length of 160 mm and 170 mm, can be used on all Orthoplan and Ortholux II biological microscopes. The reason for this compatibility is explained in more detail in the article entitled "The Excellent Leitz Microscopes with Black Enamel Finish" published in 2008.
The microscope is equipped as follows: 160 mm objectives, Fluorescence block filter with 4 positions, trinocular tube for photo/video camera support, 100W halogen illumination system for transmitted light and 100W arc lamp (HBO) for reflected light (Fluorescence).
The supported techniques are: Bright field, Episcopy, Epi-Fluorescence, COL, Rheinberg. By adding additional devices Dark field, Polarization, Phase Contrast, DIC. It also allows the use of composite techniques such as: Epi Fluorescence-DIC, COL-Rheinberg, Epi-Fluorescence-Phase Contrast, etc.
The supporting shooting devices are: professional Canon EOS 600D camera.
