Description
The Kern OZM 902 Single Boom Microscope provides extended-reach binocular inspection across crowded aerospace materials labs and PCB rework bays. Built around a horizontal sliding steel boom bar that extends 430 mm outward, this 15.0 kg freestanding system lets you position stereo optics directly over bulky workpieces without table clamps. It delivers continuous 7x to 45x magnification powered by an advanced 0.7x to 4.5x Greenough zoom engine, paired with super-widefield high-eyepoint HSWF 10x/23 mm eyepieces featuring bilateral diopter adjustments.
Surface illumination is handled by an objective-mounted 4.5W circular multi-segment LED ring light with an inline rotary rheostat, delivering shadowless daylight-balanced light over complex stepped parts. The 45-degree binocular viewing head rotates 360 degrees on its mounting collar, supported by a 380 mm vertical steel pillar. Anchoring the assembly is a solid 250 x 250 mm steel counterweight baseplate with a low-friction surface finish, running on universal 100-240V AC power with zero permanent table modifications.
Key Features of Kern OZM 902 Single Boom Microscope
An industrial binocular stereo zoom research microscope featuring a 430 mm horizontal single-arm boom stand, a 250 x 250 mm steel baseplate, and a 4.5W LED ring light. Combines 7x to 45x magnification with super-wide 23 mm eyepieces, bilateral diopters, and a 15 kg freestanding frame.
- Continuous 7x to 45x zoom magnification powered by an 0.7x to 4.5x Greenough engine
- Horizontal solid slider bar provides up to 430 mm of reach over large industrial parts
- Objective-mounted 4.5W circular LED ring light provides uniform, shadow-free illumination
- Solid 250 x 250 mm steel counterweight baseplate delivers 15.0 kg of free-standing stability
- Super-widefield HSWF 10x/23 mm high-eyepoint eyepieces provide an expansive visual field
- Greenough stereoscopic layout yields genuine 3D spatial depth for delicate tool handling
- Bilateral diopter adjustment sleeves on both ocular tubes balance visual focus
- Solid 380 mm vertical steel column accommodates deep specimen clearance heights
Single-Boom Gliding Reach & Greenough 3D Depth
Standard benchtop stands restrict movement when inspecting broad circuit panels or raw casting forgings. The solid horizontal slide bar glides smoothly through its machined carrier block, letting technicians position the microscope over awkward components with light hand pressure. Converging Greenough optical corridors provide authentic stereoscopic depth, allowing fine tweezers, deburring tools, and soldering irons to be positioned with total confidence.
High-Mass 15kg Baseplate & Shadowless Ring Light
At 15.0 kg, the thick steel baseplate anchors the workstation solidly in the center of your bench, eliminating the need for permanent mounting holes or table clamps. The circular 4.5W LED ring light surrounds the objective lens, eliminating dark corners inside deep component wells and suppressing blinding highlights on shiny solder pads. Bilateral diopter adjustment sleeves on both ocular tubes ensure tack-sharp focal balance for technicians wearing corrective eyewear.
- Free-standing heavy base requires zero table clamping, preserving valuable desk surface
- Circular ring light eliminates directional shadows on complex mechanical tooling
- Heavy locking levers clamp horizontal and vertical travel securely against focal drift
