Description
Document botanical cross-sections and cytology slides without oil mess using the Motic BA310 400x Trinocular Microscope. It gives you 40x, 100x, and 400x dry magnification powered by three CCIS Plan Achromatic objectives: 4x/0.10, 10x/0.25, and spring-loaded 40x/0.65. By omitting an oil-immersion 100x lens, this setup keeps stage plates, slide clips, and student fingers completely free of sticky residues. The Siedentopf trinocular head incorporates a fixed 20:80 optical beam splitter on its vertical photo port, sending 80% of light to an attached digital camera while maintaining active viewing through widefield N-WF 10x/20 mm eyepieces.
Transmitted illumination is supplied by an energy-efficient 3W LED cool white module that preserves daylight color balance across all brightness levels without heating live mounts. A focusable and centerable Abbe 1.25 NA condenser features an integrated iris diaphragm for fine contrast tuning. The oversized 175 x 140 mm hard-coated mechanical stage provides 76 x 50 mm of coaxial XY travel, while coaxial focus knobs operate on internal brass gears with 2-micron graduations across an 8.6 kg cast chassis running on universal 100-240V AC power.
Key Features of Motic BA310 400x Trinocular Microscope
An educational and clinical trinocular compound microscope featuring CCIS Plan Achromatic optics and an all-dry 400x magnification ceiling. Combines three dry Plan objectives with a 20:80 camera port, 3W LED lighting, a centerable Abbe 1.25 NA condenser, and a 175 x 140 mm hard-coated stage.

- Reversed quintuple nosepiece revolving on smooth ball bearings with positive click stops
- Focusable and centerable Abbe 1.25 NA condenser equipped with an iris diaphragm
- Oversized 175 x 140 mm scratch-resistant mechanical stage with 76 x 50 mm coaxial XY drive
- Coaxial coarse and fine focus drive working on precision brass gears with 2-micron steps
- Solid 8.6 kg cast-metal chassis provides complete vibration-free benchtop stability
CCIS Plan Achromatic Optics & Oil-Free Workflow
Capping magnification at an all-dry 400x ceiling prevents sticky oil messes on shared classroom equipment while delivering the resolving power needed to inspect onion epidermis and blood smears. CCIS Plan Achromatic objectives eliminate spherical field curvature across the 20 mm field of view, keeping cellular boundaries sharp right up to the visual perimeter. Spring-loaded mounts on the 40x lens protect slide cover slips from accidental mechanical strikes.
Trinocular Image Capture & Coaxial Stage Mechanics
The dedicated vertical photo port routes clean optical data to external digital C-mount cameras, letting instructors project real-time microscopic video to classroom interactive boards while students observe through the eyepieces. The oversized mechanical stage provides smooth 76 x 50 mm coordinate translation via right-hand drop-down stalks, while the 2-micron fine-focus wheel allows precise focal plane isolation without gear backlash.
- Vertical photo port routes clean optical data to external digital video capture systems
- Fixed 20:80 beam splitter allows simultaneous eyepiece observation and digital video recording
- Hard-coated mechanical stage resists scratching and chemical staining from daily slide use
