The Omano OM136C is a classic microscope - and for good reason. It is packed with professional features while being constructed to last a lifetime. Such features combine to make it both easier to use and provide enhanced viewing a and include: ergonomic 30 degree microscope head that rotates 360 degrees; Rack and pinion focusing with coaxial coarse/fine focus controls make it easier for young fingers to focus while a rack stop and slip clutch prevent slide or microscope damage; improved 6V 20W halogen illumination, a WF10x/23 eyepiece and three, parfocal, parcentered achromatic objectives: 4x, 10x, 40xS for magnification settings of 40x, 100x and 400x. The objectives are set in a click stop, rear-facing nosepiece that enables more convenient slide handling; an optional 100xS oil immersion objective can be added when bought with the microscope - as can a mechanical slide holder. We recommend the slide holder since it makes it materially easier to maneuver slides precisely. The microscope also includes a professional 1.25 N.A Abbe condenser with iris diaphragm and filter holder for ideal light control. The stage measures 125mm x 110mm with two spring-loaded stage clips to retain the slide. Illumination is available in 6V 20W halogen with variable control. Accessories include head adjustment tool, dust cover and manual.
