Description
Document clinical cytology smears with the Motic RED233 Trinocular Biological Microscope across medical university classrooms. Powered by a Color Corrected Infinity Optical System (CCIS), it delivers 40x, 100x, 400x, and 1000x magnification through four Infinity Plan Achromatic objectives: 4x/0.10, 10x/0.25, spring-loaded 40x/0.65, and spring-loaded 100x/1.25 oil immersion. The 30-degree inclined trinocular head incorporates a dedicated vertical photo port with a selectable 100:0 visual / 0:100 camera split path, paired with widefield WF 10x/20 mm eyepieces.
Transmitted light is supplied by an energy-efficient 3W LED base module that maintains constant color temperature across all dimming levels without thermal specimen distortion. A focusable Abbe 1.25 NA condenser features an integrated iris diaphragm and filter holder slot for precise contrast tuning on wet mounts. The oversized 140 x 135 mm mechanical stage features a scratch-resistant hard-coat surface and low-position coaxial XY controls (76 x 50 mm travel), while coaxial coarse and fine focus knobs track in 2-micron increments across a sturdy 7.3 kg frame operating on universal 100-240V AC power.
Key Features of Motic RED233 Trinocular Biological Microscope
A professional research-grade digital-ready biological compound microscope featuring CCIS Infinity Plan optics and a dedicated camera port. Combines 40x to 1000x magnification with a 3W LED light engine, an Abbe 1.25 NA condenser, and an oversized 140 x 135 mm mechanical stage.

CCIS Infinity Plan Optics & True Cellular Color
Color-corrected CCIS Infinity Plan objectives eliminate spherical aberration and color fringing, keeping stained plant histology and cellular smears crisp across the entire 20 mm field of view. The 3W LED lamp provides a daylight-balanced continuous spectrum that renders pink eosin and blue hematoxylin stains with authentic color saturation without thermal distortion. Spring-loaded mounts on the 40x and 100x objectives 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 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 under 1000x oil immersion.
- Vertical photo port routes clean optical data to external digital video capture systems
- Selectable beam splitter allows 100% light transfer to digital cameras for low-noise capture
- Reversed quadruple nosepiece leaves the stage completely open for rapid slide swaps
