Description
Eliminating directional shadows across watchmaking and PCB rework benches, the Kern OZL 465 Ringlight Stereo Microscope provides shadowless circular illumination on an integrated metal pillar stand. It pairs an objective-mounted 3W circular LED ring light with a continuous 0.7x to 4.5x Greenough zoom engine, delivering 7x to 45x magnification across high-eyepoint HWF 10x/20 mm eyepieces with bilateral diopter equalization. The circular ring light surrounds the objective lens, bathing metallic leads and gear teeth in even, diffuse white light.
Transmitted illumination is supplied by an independent 3W sub-stage LED panel built into the 300 x 240 mm cast-metal base, controlled by dual rotary potentiometer dials on the front deck for separate top and bottom brightness adjustments. The 45-degree binocular viewing head rotates 360 degrees across a 55 mm to 75 mm interpupillary range, supported by a rigid vertical post with dual-sided rack-and-pinion coarse focus knobs. Standing 420 mm tall and weighing 4.6 kg, this self-contained German inspection station runs on universal 100-240V AC power with internal transformer stabilization.
Key Features of Kern OZL 465 Ringlight Stereo Microscope
A compact binocular Greenough stereo zoom microscope featuring an integrated objective LED ring light and dual-channel illumination. Combines 7x to 45x magnification with shadowless surface lighting, a sub-stage 3W LED panel, widefield 20 mm eyepieces, and a 4.6 kg metal stand.
- Continuous 7x to 45x zoom magnification powered by an 0.7x to 4.5x Greenough core
- Objective-mounted 3W circular LED ring light delivers shadowless surface illumination
- Sub-stage transmitted 3W LED light source provides uniform bottom brightfield lighting
- Independent variable potentiometer rotary controls on base for both illumination circuits
- High-eyepoint HWF 10x/20 mm widefield eyepieces with bilateral diopter adjustments
- Dual-sided rack-and-pinion coarse focus drive with internal vertical gear guides
- Heavy-duty 300 x 240 mm metal base plate with frosted glass and black/white stage discs
- Solid 4.6 kg assembly mass provides steady, vibration-free benchtop support
Shadowless Ring Light & Greenough 3D Depth
Standard angled spotlights leave dark blind spots under tall surface-mount chips and inside threaded holes. The multi-segment LED ring light floods the workpiece from 360 degrees, eliminating harsh shadows and cutting down on blinding glare. The V-shaped Greenough optical pathway produces pronounced stereoscopic relief, making delicate tasks like hairspring truing, watch jewel placement, and SMD soldering feel completely natural.
Dual-Source Lighting & Pillar Stand Mechanics
Having independent dimmer wheels for both the top ring light and bottom panel gives operators total control over specimen contrast. You can dim the ring light while boosting sub-stage transmitted light to inspect translucent biological tissues, or run both together to evaluate transparent plastics with surface markings. The dual-sided rack-and-pinion focus drive provides smooth vertical travel without focal play or carriage drift.
- Circular ring light eliminates directional shadows on complex mechanical tooling
- Independent dimmers allow precise lighting ratios between surface and bottom paths
- Bilateral diopter adjustment sleeves balance visual focus for corrective lens wearers
