motic Digital BA310 biological light microscope

The Digital BA310 biological high performance microscope combines uncompromised optical clarity thanks to its integrated CCIS® (Color Corrected Infinity System) optical system with an integrated high resolution CMOS camera. The Digital BA310 has the exactly the same optical and mechanical specifications as the BA310 microscope. See all options available on the Digital BA310 Microscope Systems Diagram. A complete range of eyepieces and objectives are available to configure the Digital BA310 for your application. (CMOS and photo adapters are not available for the Digital BA310 due to the integrated camera). The Motic® Digital BA310 is designed for the rigors of daily routine work in the demanding applications of Professional Cytology, Hematology and Pathology laboratory settings. The Motic® Color Corrected Infinity Optics(CCIS®) with newly designed EF-N Plan objectives provides high resolution and excellent optical performance for all microscopy needs. The Digital BA310 is upgradeable to include additional contrast methods. These features ensure this model will offer long term functionality to all user levels in a variety of applications.

The Digital BA310 is a superior microscope meeting the rugged demands for daily work needs in a Professional laboratory setting. The Digital BA310's 30W illumination provides the user with a powerful and adjustable light source to meet both delicate and detailed lighting requirements for all sample types. The fully featured Koehler illumination of the Digital BA310 helps in highlighting even the weakest stained specimens.

The Motic® Color Corrected Infinity Optics CCIS® and the EF-N Plan Achromat objectives provide optimal image contrast through newly designed multi-layer lens coatings. The fully corrected tube lens and subsequent intermediate image without color fringing is now fully accessible through both eyepiece and the trinocular port making digital images as crisp and clear as those seen through the eyepieces. The Digital BA310's large, hard coated and chemical resistant stage, with an expansive 76x50mm travel range, includes a new slide holder with improved tighter grip. This ensures easy and repeatable scanning of numerous slides in all daily routines. A complete range of options and accessories are available to configure the Digital BA310 to your application. All options are shown in the Digital BA310 microscope systems diagram.

Motic Digital BA310 observation tube

Siedentopf Observation Tube

The Digital BA310's sidentopf observation tube is designed with an ergonomic viewing angle of 30° and incorporating an interpupillary distance of 55-75mm. The Digital BA310's observation tubes guarantee fatigue free viewing for hours. An optional large field of view (20mm) enables fast and comfortable screening of a specimen.

BA210 standard eyepieces


The standard eyepieces are made of high quality optical glass and have a high-eyepoint for eyeglass wearers. The eyepieces provide consistent diopter adjustments for both eyes. This enables perfect usage of reticles for measuring, counting, etc. Standard lockable eyepieces guard against inadmissible removal.

Motic Digital BA310 quintuple revolving nosepiece

Reversed Quintuple Turret Revolving Nosepiece

The Digital BA310 has the capability for mounting up to five quality objectives, allowing easy access to the slide. Precision positive click-stop mechanism ensures precise alignment of objectives.



To improve overall optical performance of the Digital BA310, Motic® introduces a newly designed generation of Plan Achromatic Objectives made of high quality optical glass: CCIS® EF-N Plan. These new lenses are now multilayer coated for improved contrast to enhance images even with weak slide staining. Together with a newly calculated tube lens, the result is a fully coated, perfected intermediate image without colored fringes. RMS thread.

Fine/Coarse Coaxial Focusing

Coaxial course and fine focusing mechanism is precision brass manufactured using a reliable triangular rail system, with adjustable tension, providing durable operation of the microscope. The focusing range is 25mm with minimum increments of 2µm.

Motic Digital BA310 microscope condenser


To ensure the best possible illumination quality, the Digital BA310 has a full Koehler feature giving complete freedom to set the height of the condenser, so counting chambers with unusual height dimensions can be used.



The Digital BA310 introduces a new collector lens assembly with a secure, threaded holder for the frequently used blue daylight filter, which is an integral part of the illumination package. The fixed cap prevents the filter from dropping and breaking when the instrument is moved or stored.

Motic Digital BA310 micoscope Mechanical Stage

Mechanical Stage

The Digital BA310 offers an optional left/right hand control and the slide holder enables consistent sample movement across a 76x50mm range with a stage of 175mm x 145mm. The Digital BA310 also offers a hard coated surface, resistant against routine usage abrasion and most lab chemicals.

Light source with integrated power supply

The universal power supply (110-240V) is integrated inside the frame for increased stability. The 6V/30W halogen lamp with intensity controls provides bright and even illumination at any magnification.

Anti-Fungus Coating

To protect the system from fungus formation in high-humidity environments, an anti-fungus coating is used to prolong the life of both microscope and objectives.

Mechanical Stage

Simple Phase Contrast

Offered as an option, simple phase contrast is available for magnification 10x and 40x.

Phase Contrast

Also available is the 5-position turret type phase contrast condenser and CCIS® phase plan objectives.

ba210 simple darkfield slider

Simple Darkfield

Darkfield is possible with a separate DF slider.

BA310 polarizer - analyzer

Simple Polarization

Convenient and simple, the Digital BA310 polarization system consists of an analyzer filter placed between the head and body; and a polarizer filter placed on top of the collector lens.


The importance of documentation has expanded into every aspect of microscopy, as has the method of documentation.

3.0 Mega Pixel digital CMOS camera

The 3.0 Mega Pixel digital 1/2" CMOS camera has an image resolution of 2048 x 1536 pixels, fast 480MB/sec data transfer over USB 2.0 port and comes complete with Motic® Image Plus 2.0 software
