Compound trinocular microscope provides 12 magnification steps from 40x to 5000x with double-layer mechanical stage and LED illumination
This trinocular compound microscope provides 12 magnification settings from 40X to 5000X using 10X, 25X and 2X eyepieces with 4X, 10X, 40X and 100X oil objectives. It suits laboratory work, biological study and educational use where detailed visual inspection is required. The expansion interface allows connection to a computer or LCD screen for shared viewing.
The built-in LED light source is adjustable to suit different specimens and ambient conditions. A 1.25NA condenser with iris diaphragm controls contrast and depth of field. The microscope operates on AC 100-240V at 50/60Hz via the included 5V2A adapter, drawing minimal power during extended sessions.
A double-layered metal stage measuring 115x125 mm moves across a 72x30 mm range to position slides precisely. Coarse focus travels 14 mm and fine focus 1.3 mm for sharp detail. The package includes a phone holder, 100 cover glasses, five carrier glasses, a test tube, a petri dish and a full accessory set.

The trinocular head mounts on the main tube; rotate it until the eyepiece tubes sit level and the phototube faces the camera port, then tighten the locking screw so the 1.25NA condenser stays centred.
The 4X, 10X, 40X and 100X oil objectives, the 10X and 25X eyepieces, the 2X auxiliary lens and the 1.25NA condenser with iris diaphragm all require periodic cleaning; immersion oil must be wiped from the 100X objective after each session.
At 5000X the 1.3 mm fine-focus range is the first limit encountered; depth of field narrows so that even the smallest focus step exceeds the optimal plane.
