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? microscope head that rotates 360?; 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 or LED 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 at a discounted price 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 either 6V 20W halogen or rechargeable LED with variable control. Accessories include head adjustment tool, dust cover and manual. Lifetime Limited Warranty. Omano® is a registered trademark of The Microscope Store, LLC. All rights reserved.
