Description
Perform advanced cellular tissue audits without thermal specimen damage using the Kern OBL 127 Binocular Microscope. Operating on a high-performance infinity-corrected optical pathway, it delivers 40x, 100x, 400x, and 1000x magnification through four Infinity E-Plan objectives: 4x/0.10, 10x/0.25, spring-loaded 40x/0.65, and spring-loaded 100x/1.25 oil immersion. Anti-fungus treated lenses provide flat-field optical correction across the 20 mm field of view, keeping cellular structures sharp from center to margin.
Transmitted illumination is supplied by an energy-efficient 3W LED base module that maintains constant color temperature across all dimming levels without thermal specimen drift. A height-adjustable Abbe 1.25 NA condenser features an integrated iris diaphragm, rack-and-pinion focus mechanics, and a filter slot track structure. The 30-degree inclined binocular head rotates 360 degrees, fitted with paired widefield WF 10x/20 mm eyepieces with left-tube diopter adjustment across a 50 mm to 75 mm interpupillary span. The 145 x 130 mm double-layer mechanical stage provides 76 x 52 mm of coaxial XY travel, while coaxial coarse and fine focus knobs feature 2-micron graduations across a 6.5 kg cast chassis powered by universal 100-240V AC power.
Key Features of Kern OBL 127 Binocular Microscope
A professional laboratory binocular biological compound microscope featuring Infinity E-Plan optics and cool 3W LED illumination. Combines 40x to 1000x magnification with an Abbe 1.25 NA condenser, double-layer mechanical stage, and 2-micron coaxial focusing.

- Solid 6.5 kg cast-metal chassis provides complete vibration-free benchtop stability
Infinity E-Plan Optics & Cool 3W LED Illumination
Infinity-corrected E-Plan optics flatten image curvature across the 20 mm field of view, keeping stained tissue margins crisp from center to edge. The 3W LED lamp provides a daylight-balanced continuous spectrum that renders biological stains with authentic color saturation without thermal distortion. Spring-loaded mounts on the 40x and 100x objectives protect slide cover slips from accidental mechanical strikes.
Coaxial Focus Mechanics & Stage Translation
The double-layer mechanical stage provides smooth 76 x 52 mm coordinate translation via right-hand drop-down stalks, keeping hand movements relaxed during long diagnostic shifts. Coaxial coarse and fine focus knobs operate on internal gear tracks with calibrated 2-micron division markings, giving technicians delicate focal plane control. The reverse-facing nosepiece keeps objective lenses angled safely back toward the stand neck during slide swaps.
- Reversed quadruple nosepiece leaves the stage completely open for rapid slide swaps
- Abbe condenser iris diaphragm allows fine contrast tuning across all objective powers
- Low-position coaxial XY controls reduce wrist fatigue during high-volume sample rounds
