Motic® BA310MET and BA310MET-T
Advanced Metallurgical and Ceramics Microscopes

Motic BA310MET Metallurgical Microscope   Motic BA310MET-T Metallurgical Microscope
Motic® BA310MET Trinocular
Motic® BA310MET-T Binocular

The Motic® BA310MET series is an affordable and powerful line of robust incident (reflective) light (BA310MET) and dual illumination (BA310MET-T) metallurgical microscopes.

Designed for observing all opaque materials including minerals, metals and ceramics, the BA310MET is ideal for applications where affordability and ease of use are key demands, such as Educational Fields, Semi-Conductors, Engineering and Material Science as well as Industrial Quality Control.

The BA310MET-T model adds a transmitted light option which allows viewing of transparent and interior bore samples and greatly increases the number of industrial applications.

All models feature the powerful and adjustable Epi-Illuminator with a 12V/50W halogen bulb light source for reflective samples. The halogen bulb is easily replaced with an LED module (available in 4500K or 6000K color temperature) to increase illumination options. A built-in field diaphragm and aperture diaphragm help to optimize image quality by reducing stray light and increasing contrast.

Siedentopf Observation Tube

Siedentopf Observation Tube

The BA310METs Siedentopf observation tube is designed with an ergonomic viewing angle of 30° and incorporating an interpupillary distance of 55-75mm. The BA310METs observation tubes guarantee fatigue-free viewing for hours. A large field view (20mm) enables fast and comfortable screening of a specimen. The trinocular tubes allow digital documentation and integration to a wide variety of digital cameras, with a standard 20/80 light split for the trinocular photo video port. An optional trinocular tube with an erect image and a 50/50 light split is also available.

BA310MET Standard eyepieceE  


The standard eyepieces, N-WF 10x/20 with high eyepoint for eyglass wearers, made of high quality optical glass, provide consistent diopter adjustments for both eyes. This enables perfect usage of reticles for measuring purposes. Lockable countersunk screws to fix the eyepieces prevent inadmissable removable and confirm the dedication of Motic® to student-proof quality. Rubber eye cups are standard. Eyepieces with FOV 22mm are optional.


Reversed Quintuple Turret Revolving Nosepiece

The BA310MET has the capability of mounting up to five quality objectives. A precision click-stop mechanism ensures precise alignment of objectives. The ball bearing 5-fold nosepiece shows a reversed orientation of the lenses and ensures parcentration and repeatability with every magnification change.



With the BA310MET, Motic® introduces a new generation of Metallurgical LM Plan objectives.  These plan objectives are made of high quality glass and employ Motic’s CCIS® Optical  Concept.  Multi- layer coating ensures improved contrast and image quality and the tube lens provides a completely corrected intermediate image, accessible  by the photo port exit of the trinocular models. Documentation, therefor, is based on maximum image quality. RMS thread.

10x 0.25 17.5
20x 0.40 8.1
50x 0.55 8.4
100x 0.80 2.0



The Epi-Illuminator on the BA310MET models is based on a 12V/50W Halogen light source. The unit’s power supply is separated from the stand to avoid unnecessary heat surrounding the microscope.

The Halogen bulb can be replaced by an LED module (either 4500K or 6000K) simply plugged into the Halogen lamp socket. The adjustable field diaphragm and aperture diaphragm guarantees homogenous illumination and image contrast quality. The simple polarization set enables a useful “POL contrast” and helps improve image contrast, especially in low power objectives.


The BA310MET-T models add a standard Koehler 6V/30W halogen transmitted light illuminator with field diaphragm. Replacement of the halogen bulb with a LED module (4500K or 6000K) is a simple plug-in option. The BA310MET-T microscopes feature a new N.A. 0.85 condenser to ensure the best possible illumination. A very secure screw on filter holder is standard.

Illumination for BA310MET-T

Mechanical Stages

Depending on the application, three different stages are available for the BA310MET. All stages provide a convenient sample movement with their triple plate design.

The standard stage for the BA310MET is 180 x 140mm (7" x 5-1/2") and has a travel range of 75 x 50mm (3" x 2").

The BA310MET-T models come with a 240 x 140mm (9-1/2" x 5-1/2") stage which will support larger samples. The movement is 75 x 50mm (3" x 2"). A glass stage insert is provided and a slide holder is optional.

For extended demands, a 300x 180mm (11-7/8" x 7") stage with a movement of 150 x 100mm (6" x 4") can be supplied with the BA310MET-T, as a special order non-stock option.

ba310met digital documentation trinocular microscope  

Digital Documentation

The combination of the Motic® BA310MET Trinocular or the BA310MET-T Trinocular and any of the Moticam® series of CMOS cameras will deliver excellent live images which can be easily stored for future use. All Motic® cameras come equipped with software to transform the BA310MET Trinocular series into an analysis and documentation station.

C-mount adapters of 1x, 0.65x and 0.5x, chosen in relation to chip size of digital camera used, are needed to connect any C-mount digital camera to trinocular port. Should you choose a Motic® or third-party camera, Motic® provides a range of C-mount adapters which are necessary for trinocular port attachment.

Standard Photomicrography

Use of a traditional SLR style camera requires a trinocular version of the BA310MET. A mechanical T-mount adapter combined with a photo eyepiece (2.5x or 4x) must be fitted to the microscope.

A T/T2 adapter (supplied by the camera manufacturer) may also be necessary for this application.
