Description
Screen biological specimens and audit electronic solder connections using the Motic SMZ-140-N2LED Binocular Microscope dual-illumination workstation. It delivers continuous 10x to 40x magnification powered by a 1.0x to 4.0x Greenough optical zoom engine (4:1 zoom ratio). The 45-degree binocular viewing head rotates 360 degrees, fitted with paired widefield WF 10x/20 mm eyepieces with bilateral diopter adjustments across a 54 mm to 76 mm interpupillary span, providing a comfortable working posture during long inspection shifts.
Built on a compact 237 x 170 mm metal base plate, the stand incorporates dual independent cold 3W LED illuminators: an angle-adjustable top spotlight for surface topography and an integrated sub-stage transmitted cluster for transparent slides, managed by dual thumbwheel dimmers. The coaxial rack-and-pinion focus carriage provides 49 mm of vertical stroke along a 210 mm solid post (25 mm diameter) with adjustable internal tension bands. Weighing 6.2 kg, this reliable benchtop instrument runs on universal 100-240V AC power with an 80 mm fixed working distance.

Greenough 3D Depth & Parcentric Zoom Performance
The V-shaped Greenough optical pathway produces pronounced stereoscopic relief, making delicate hand-tool work like tweezer sorting and micro-soldering feel natural and precise. Parcentric optical engineering ensures specimens stay centered in the field of view while zooming from 10x macro overviews down to 40x detail checks. Achromatic multi-coated lenses preserve high-contrast color neutrality across the entire zoom curve.
Dual 3W LED Illumination & Compact N2LED Stand
The top 3W LED spotlight adjusts in angle to highlight surface flaws and micro-burrs with oblique light, while the cold sub-stage LED cluster illuminates biological mounts without thermal drift. Independent thumbwheel dimmers on the base deck allow separate brightness regulation. The rack-and-pinion focus carriage moves without gear lash, while the 237 x 170 mm baseplate keeps the entire assembly planted on crowded repair benches.
- Cold 3W LED illuminators protect temperature-sensitive electronic adhesives
- Compact baseplate preserves valuable counter space in busy assembly and repair cells
- Coaxial rack-and-pinion focus drive with tension control prevents vertical carriage drift
