Description
Operating with a 113 mm working distance and 35-degree viewing angle, the Motic SMZ-168-BP Binocular Stereo Microscope delivers fatigue-free manual sorting across watchmaker service centers and micro-assembly benches. Its 35-degree inclined viewing tubes keep your neck in a neutral, relaxed posture during long shifts, while an advanced 0.75x to 5.0x Greenough optical zoom engine (6.7:1 zoom ratio) delivers continuous 7.5x to 50x magnification. Paired ultra-widefield WF 10x/23 mm high-eyepoint eyepieces provide an expansive 23 mm field of view with bilateral diopter adjustments.
Built on a low-profile 280 x 220 mm solid metal baseplate, this passive 4.8 kg inspection platform features a 225 mm vertical steel post with an adjustable split-ring safety collar. The rack-and-pinion coarse focus block features adjustable tension regulation bands to stop carriage droop over time, while the solid, unperforated baseplate is treated with a chemical-resistant enamel that shrugs off solvent spills and watch oils. Completely passive in construction, this stand requires zero electrical cords, operating as an ultra-stable foundation for precision micro-mechanism assembly tables.
Key Features of Motic SMZ-168-BP Binocular Stereo Microscope
A high-performance unilluminated continuous zoom binocular stereo microscope featuring an ergonomic 35-degree viewing angle and 113 mm working distance. Combines 7.5x to 50x magnification with an ultra-wide 23 mm field of view, chemical-resistant plain base, and bilateral diopter adjustments.

- Ergonomic 35-degree inclined binocular viewing head reduces neck strain during long shifts
- Large 113 mm fixed working distance provides ample vertical room for tweezers and hand tools
- High-eyepoint ultra-widefield WF 10x/23 mm eyepieces with bilateral diopter adjustments
- Solid 225 mm vertical steel pillar column with adjustable mechanical safety stop collar
- Oversized 280 x 220 mm plain metal baseplate finished in chemical-resistant enamel
- Rack-and-pinion coarse focus block with adjustable internal tension control bands
- Passive non-electrical chassis accepts external LED ring illuminators and gooseneck spot lamps
Greenough 3D Depth & 35-Degree Ergonomic Posture
Standard 45-degree microscope tubes force technicians to crane their necks downward, leading to chronic cervical spine fatigue. The 35-degree viewing inclination on the SMZ-168 promotes an upright seating posture, letting operators work comfortably for hours. Converging Greenough optical paths provide authentic stereoscopic relief, making delicate tasks like hairspring truing and watch jewel seating feel completely natural. Anti-reflective multi-coatings preserve high-contrast edge resolution without color fringing.
113mm Tool Clearance & Solid Metal Pillar Base
The 113 mm working clearance is a massive operational asset: you can work under the objective with soldering tips, tweezers, and loupes without blocking light or scratching front lenses. The solid unperforated baseplate provides a flat, rigid staging area that keeps small screws from rolling into lighting wells. The split-ring safety collar clamps around the vertical post to physically catch the focus block if an operator loosens the main clamp too quickly.
- 35-degree viewing angle relieves chronic neck and upper back fatigue during long shifts
- Constant 113 mm working distance ensures tool access without focal interference
- Mechanical safety stop collar ring provides physical drop protection during vertical realignments
