Description
Maneuver high-magnification stereo optics across multi-tiered assembly fixtures using the Kern OZM 982 Spring Balance Microscope. It gives you 7x to 45x continuous zoom magnification powered by an advanced 0.7x to 4.5x Greenough engine (1:6.4 zoom ratio). The gas-spring counterbalanced articulated arm extends 880 mm horizontally with 400 mm of vertical lift flight, letting you glide the optical head over large parts with light finger pressure. When released, internal gas springs lock your position instantly in three dimensions without focal settling.
Instead of occupying desk space with a heavy baseplate, the arm anchors to table margins via an industrial dual-screw steel clamp. Surface lighting is handled by an objective-mounted 4.5W circular multi-segment LED ring light with an inline rotary rheostat, delivering shadowless illumination over complex stepped contours. The 45-degree binocular viewing head rotates 360 degrees, fitted with super-widefield high-eyepoint HSWF 10x/23 mm eyepieces featuring bilateral diopter equalization across a 52 mm to 76 mm interpupillary range. The entire 14.0 kg mechanical assembly operates on universal 100-240V AC power with zero desk-drilling requirements.
Key Features of Kern OZM 982 Spring Balance Microscope
An industrial binocular stereo zoom microscope featuring an 880 mm gas-spring counterbalanced articulated arm and a heavy table clamp. Combines 7x to 45x magnification with super-wide 23 mm eyepieces, zero-gravity vertical lift, and a 4.5W LED ring light for fatigue-free inspection.
- Continuous 7x to 45x zoom magnification powered by an 0.7x to 4.5x Greenough engine
- Gas-spring counterbalanced articulated arm delivers 880 mm reach and 400 mm vertical lift
- Heavy-duty dual-screw steel table clamp anchors rigidly to bench lips without drilling
- Objective-mounted 4.5W circular LED ring light provides uniform, shadow-free illumination
- 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
- Complete 14.0 kg mechanical assembly powered via external universal 100-240V AC adapter
Zero-Gravity Gas-Spring Arm & 880mm Articulated Reach
Standard friction arms require two hands to loosen and lock every time you change inspection heights. This gas-spring arm eliminates that hassle: grab the head, push or pull it into position, and let go. The internal springs offset payload weight perfectly, so the microscope floats right where you leave it. When unmagnified assembly begins, simply push the entire linkage back against the wall to reclaim your workbench surface.
High-Power 4.5W Ring Light & Super-Wide 23mm Field
Inspecting deep holes or reflective solder pads often creates blinding highlights. The 4.5W multi-segment ring light bathes parts in even, daylight-balanced white light, washing away harsh shadows. Stepping up to a 23 mm field number gives you noticeably more situational context when scanning printed circuit boards or evaluating jewelry engravings, reducing the need to constantly nudge parts under the lens.
- Gas-spring articulated arm provides effortless zero-gravity positioning over large parts
- Bench-clamp base preserves complete tabletop surface area for diagnostic equipment
- Concentric ring illuminator eliminates harsh shadows on complex machined metal parts
