Viewing Heads: Model MA952 is the Siedentopf-type binocular head and Model MA953 is the trinocular head for camera integration. Each head has the 23.2 mm eyetubes inclined at 30 degrees with the left eyetube having graduated diopter settings. The interpupillary distance is adjustable between 53 mm - 75 mm. An 80/20 beamsplitter for the trinocular tube can be engaged for photo work. Each head has the new integrated reticle angle compensation system. When the IP distance or number is changed, the crossline reticle remains perpendicular in the FOV. Eyepieces: 10X Widefield High Eyepoint eyepiece F.N.20, 10X Widefield High Eyepoint focusable eyepiece that has a 21 mm crossline reticule and guide pin, and 10X Widefield High Eyepoint Compensating Focusing eyepiece, F.N.20 with Walton & Beckett reticle are standard. Objective Changer: The smooth-operating, ball bearing mounted, quadruple nosepiece provides effortless objective changes. Objectives: Assortment of U. Planachromat Phase and S. Planachromat Polarizing Infinity Corrected objectives are available. Stage: Ceramic coated 360 degree rotatable fully indexed stage with vernier and stage clips. Condenser: Strain free Abbe condenser, N.A. 1.25 with centerable annuli for 10X, 20X, 40X phase or 10X, 20X, 40X dispersion staining objectives in sliding mount, with iris diaphragm and dovetail mount. Illumination: Powerful 30 watt transmitted light Koehler halogen illumination provides enhanced image quality and brightness for the observation of specimens. Accessories: All MT6800 series models come with a first order red compensating plate (also called gypsum or sensitive tint plate), an analyzer in sliding mount, bertrand lens, blue clear and green interference filters, centering telescope, and stage micrometer.
