Infinity-Corrected Compound Microscope, Binocular, Plan 4x/100xR & Phase 10x/40xR

Infinity-corrected optics maintain parfocality even when an auxiliary component is addedperfect for advanced studies and professional applications|Ergonomic 30 inclined Siedentopf head provides operator comfort|20 mm eyepieces increase field of view|Reversed nosepiece allows clear access to stage|Smooth, ball-bearing mounted quad objectives for precise positioning of objectives|Shielded iris diaphragm for added protection|All metal internal parts offer durability|Binocular compound microscope includes infinity-corrected plan 4x (0.10 N.A.), infinity phase 10x (0.25 N.A.), infinity phase 40xR (0.65 N.A.), and infinity-corrected plan 100xR oil immersion (1.25 N.A.) objectives|Comes with phase contrast five-position Abbe condenser N.A. 1.25 (BF, DF, Phase 1, Phase 2, Phase 3)|Limited lifetime warranty|The M17 series compound microscopes feature infinity-corrected optics that allow one or more auxiliary components (illuminators or polarizer) to be added without altering the alignment between the objective and tube lens. Even with added components infinity-corrected optics produce exactly 1x magnification allowing easy comparison between specimens. These research level microscopes feature a 30 inclined eyepieces with diopter and interpupilllary adjustment from 54 to 76 mm. A bright 3 W LED illumination system and widefield 20 mm eyepieces provide a sharp image. The 100xR objective is spring-loaded and sealed to protect optics from contact or oil damage. Optically coated Abbe 1.25 N.A. brightfield condenser allows maximum transmission and enhanced contrast. Large 14.2 x 14 mm (5-3/4" x 5-1/2"), low-drive mechanical stage offers precise scanning of your specimen.
