Description
Meiji Techno Phase Contrast optical components needs to be aligned to the condenser annulus with the phase plate in the objective rear focal plane with a phase telescope, that inserts into one of the microscope eyepiece observation ports. The phase contrast annulus is used in the substage condenser on Meiji Techno’s upright microscope within the condenser turret. The Phase ring in the condenser must be specifically matched to the particular Phase objective equipped with a corresponding phase plate annulus. For example, the Phase 10X and Phase 20X both of which contain a phase plate will require a condenser annuli having different diameters that correspond to the objective magnification and N.A. (Numerical Aperture). By properly matching the Meiji Techno Condenser annulus to the objective phase plate, the Meiji Techno Phase microscope can be aligned to superimpose illuminating light rays passed through the annulus onto the Phase ring of the objective to achieve proper Phase contrast illumination.
The Ph1 condenser annulus , which contains the smallest aperture, is designed to be used with the lower power 10X and 20X Phase objective. Intermediate magnification objective 40X Phase utilize the Ph 2 annulus, while the highest power and N.A. 100X objective require the Ph 3 annulus, which requires the largest phase annulus.
The Ph1 position in the Phase Condenser Turret facilitates Objectives Phase 10X and Phase 20X
The Ph2 position in the Phase Condenser Turret facilitates Objectives Phase 40X
The Ph3 position in the Phase Condenser Turret facilitates Objectives Phase 100X

VIEWING HEADS
Model MA815/05 is the Siedentopf-type binocular head and Model MA816/05 is the trinocular head for camera integration. Each head has the eyetubes inclined at 30 ° with the left eyetube having graduated diopter settings. The interpupillary distance is adjustable between 53mm – 75mm. An 80/20 beamsplitter for the trinocular tube can be engaged for photo work.The optional MA957/05, Ergonomic Binocular Viewing Head, has the inclination adjustable from 10 to 50 degrees to fit users of different heights. The Ergonomic Trinocular model comes with the MA958, photo/video attachment with sliding 80/20 beam-splitter
