Description
The Motic BA310 MET Trinocular Metallurgical Microscope provides high-contrast reflected brightfield inspection across standard alloy testing desks. Operating on a Color Corrected Infinity Optical System (CCIS), it delivers 50x, 100x, 200x, and 500x magnification via four Long Working Distance (LWD) LM Plan Achromatic objectives: 5x, 10x, 20x, and 50x. The Siedentopf trinocular head incorporates a fixed 20:80 optical beam splitter and a top-mounted vertical photo port, allowing simultaneous digital camera capture while viewing through high-eyepoint N-WF 10x/20 mm eyepieces.
Reflected illumination is supplied by an upper EPI attachment carrying a 12V/50W quartz halogen lamp house with integrated field and aperture diaphragms for glare-free Köhler contrast. The 180 x 140 mm mechanical stage features a scratch-resistant hard-coat surface, metal slide inserts, and low-position coaxial XY translation controls (75 x 50 mm travel). Supported by coaxial coarse and fine focus knobs operating on internal brass gears with 2-micron fine division markings, this 10.8 kg cast-metal frame (400 x 220 x 450 mm) runs on universal 100-240V AC power with integrated polarizer filter slots.
Key Features of Motic BA310 MET Trinocular Metallurgical Microscope
A professional upright metallurgical trinocular microscope engineered for reflected brightfield inspection, alloy grain mapping, and failure analysis. Combines four CCIS LM Plan LWD objectives with 50W quartz halogen EPI-illumination, a 75 x 50 mm mechanical stage, and a 20:80 camera port.

- Solid 10.8 kg cast-metal chassis provides complete vibration-free benchtop stability
Reflected 50W Halogen Köhler Lighting & LM Plan Optics
Opaque mineral sections, semiconductor packages, and polished metallurgical mounts reflect light back through the objective lens, requiring intense incident illumination. The 50W quartz halogen lamp house floods the specimen plane with a warm continuous spectrum that brings out true grain boundaries and etching contrast. Built-in aperture and field diaphragms allow operators to eliminate internal barrel reflections and dial in optimal optical resolution on shiny alloys.
Mechanical Stage Scanning & Trinocular Video Output
The 180 x 140 mm mechanical stage provides smooth 75 x 50 mm coordinate translation via right-hand drop-down stalks, letting technicians scan metallurgical pucks systematically without touching specimen surfaces. The vertical photo port routes clean optical data to external digital C-mount cameras, letting failure analysis engineers stream high-resolution inspection footage straight to customer reports while actively viewing through the oculars.
- Köhler illumination diaphragms eliminate stray reflections on polished metal faces
- Integrated polarizer and analyzer filter slots support basic polarization surface checks
- Vertical camera channel allows simultaneous eyepiece viewing and digital documentation
