Part of the affordable OM118 series, the OM118-B4SL is a binocular compound microscope that includes four objective lenses and a full, double-layered mechanical stage that optimizes slide handling. In our opinion, a mechanical stage is an indispensable tool for any serious student. Four levels of magnification, 40x, 100x, 400x and 1,000x are derived from two WF10x eyepieces and 4x, 10x, 40xS and 100xS oil immersion, objectives.

Like the monocular sister microscopes (OM118-M3 and M4), this binocular version was introduced in 2010 as a cheaper alternative to our ever popular Omano OM136C and OM36 series. It has similar optics to the OM36C, but lacks some of the finesse in design and construction. The microscope includes a 5-year Omano limited warranty.


The Omano OM118-B4SL includes a binocular microscope head that is inclined at an ergonomic 45 degrees. The head rotates through 360 degrees for flexible viewing positions. There are two Wide Field WF10x eyepieces that combine with four parcentered, parfocal achromatic objectives lenses, (4x, 40x spring, 100x spring oil immersion) for magnification levels of 40x, 100x, 400x and 1,000x. The objectives are set in a quadruple nosepiece. Both oculars include diopters that enable individual eye focusing while the head can be adjusted through 55-75mm to adapt for different interpupillary distances.

Stage & Focus

The primary difference between this microscope and the Omano OM118-B4 is in the stage. This microscope includes an integrated, double-layered mechanical stage as opposed to a detachable mechanical slide holder on the OM118-B4. In the final analysis, an integrated mechanical stage is the only answer for any serious student or professional microscopist.

While a mechanical slide holder is an improvement on a plain stage, a mechanical stage includes full graduated X/Y movement (18mm x 70mm) with coaxial coarse/fine focus controls. Such coaxial controls enable a student to move the slide without looking up from the eyepiece; for regular users this benefit is an indispensable convenience.

Focusing includes high quality rack and pinion mechanics for longer life and coaxial focus controls for easier focusing. We recommend coaxial coarse/fine focus controls since they enable 'eyes down' focusing. In other words, the viewer does not constantly need to look up in order to find the other focus control. This benefit is important in enhancing a student's experience and therefore in encouraging a more sustained interest in the microscope.

Safety features include a rack stop to ensure that the stage does not impact with the objectives and thereby break the slides and a slip clutch control to mitigate the risk of damaging the focus controls through over extension.

Condenser & Illumination

The condenser is Abbe 1.25 N. A with iris diaphragm for optimal adjustments. Transmitted LED illumination includes variable intensity and is rated for 110V/120V.

Optional Summit Series Camera

All the Summit Series microscope cameras stand out for remarkable color resolution as well as a large color palette for improved color resolution and sensitivity. Critically, they are free from the smearing and blur that characterizes other systems in this price range. In addition, the included 0.5x reducing lens makes for an image that is significantly closer to that seen through the eyepieces with the naked eye. Robust documentation and measuring software is included with all the OptixCam cameras as well as four different mounts: C/CS Mount, 23mm eyepiece adapter, 30mm and 30.5mm collars so they will fit almost any microscope.

Other features include fast refresh rates, auto/ manual exposure and white balance control, full screen live imaging, time lapse photography and user-friendly, image capture. In short, these microscope cameras offer a well-designed package at an affordable price. We recommend them for any standard photomicrography application where the primary requirements are image capture and documentation.

Camera Accessories
