Description
Classify geological rock grains and inspect unpowered mechanical assemblies using the Optika SZO-1 Binocular Stereo Microscope. Built on a basic unpowered pillar stand, this passive 4.2 kg inspection platform requires zero electrical connections, making it an ideal workhorse for classroom benches, geology sorting desks, and production areas utilizing external ambient or fiber-optic lighting. It delivers continuous 6.7x to 45x magnification powered by an 0.67x to 4.5x Greenough twin-path optical core with calibrated click-stop detents.
Paired extra-widefield high-eyepoint WF 10x/23 mm eyepieces provide an expansive 23 mm field of view with bilateral diopter equalization across a 55 mm to 75 mm interpupillary span. The 45-degree binocular tubes rotate 360 degrees on the mounting collar, while an extensive 110 mm fixed working distance leaves abundant clearance for geological hammers, tweezers, and probes. The 210 x 270 mm flat base platform is fitted with a reversible black and white contrast stage plate and dual metal specimen clips, supported by a 280 mm vertical pillar with smooth coaxial focus tracking.
Key Features of Optika SZO-1 Binocular Stereo Microscope
An unilluminated laboratory binocular stereo zoom microscope system featuring pre-calibrated zoom click-stops on a compact pillar stand. Combines 6.7x to 45x magnification with an ultra-wide 23 mm field of view, 110 mm working distance, reversible contrast plate, and unpowered passive design.
- Continuous 6.7x to 45x zoom magnification powered by an 0.7x to 4.5x Greenough engine
- Pre-calibrated detent click-stops along the zoom dial ensure repeatable measurement indexing
- Large 110 mm operational working distance leaves ample room for tools and geological samples
- Extra-widefield high-eyepoint WF 10x/23 mm eyepieces on a 45-degree inclined binocular head
- Unpowered mechanical framework structure requires zero electrical network connections
- Oversized 210 x 270 mm flat base platform fitted with reversible black/white stage plate
- Coaxial coarse focus adjustment tracker integrated onto the structural pillar mounting collar
- Lightweight 4.2 kg assembly allows rapid relocation across workshop counters
Greenough 3D Depth & Calibrated Click-Stop Zoom
Twin converging optical pathways deliver pronounced stereoscopic relief, making delicate hand-tool work like tweezer sorting and mineral facet orientation feel natural and precise. The internal click-stop detents along the zoom dial are a major practical asset for quality assurance logs: you can click into calibrated steps, verify component tolerances, and return to the exact same magnification setting later without focal drift.
110mm Tool Clearance & Unpowered Pillar Stand
The 110 mm working clearance is a massive operational asset: you can work under the objective with scribes, tweezers, and loupes without blocking ambient room light or scratching front lenses. The solid unpowered baseplate provides a flat, rigid staging area that eliminates cord clutter on shared classroom tables. Reversible black and white contrast plates make light or dark mineral grains pop visually.
- Unpowered design allows flexible deployment anywhere in field labs or classrooms
- Tactile click-stop zoom dial ensures consistent magnification settings for quality logs
- Constant 110 mm working distance ensures tool access without focal interference
