Kern OBF 123 Binocular Plan 3W LED Laboratory Gear

Description

Screen routine clinical cytology smears and veterinary samples using the Kern OBF 123 Binocular Microscope. Operating on a finite 160 mm optical pathway, it delivers 40x, 100x, 400x, and 1000x magnification via four Plan Achromatic 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 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/18 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 75 x 40 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 OBF 123 Binocular Microscope

A professional laboratory binocular biological compound microscope featuring Plan Achromatic flat-field 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.

• Plan Achromatic finite objectives: 4x, 10x, spring-loaded 40x, and 100x oil immersion
• Reversed quadruple nosepiece revolving smoothly on precision ball bearings
• Sub-stage transmitted 3W LED light module with continuous electronic dimmer
• Height-adjustable Abbe 1.25 NA condenser equipped with an adjustable iris diaphragm
• Double-layer 145 x 130 mm mechanical stage with 75 x 40 mm low-drop coaxial XY drive
• Coaxial coarse and fine focus drive with calibrated 2-micrometer fine division markings
• Widefield high-eyepoint WF 10x/18 mm eyepieces with left-tube diopter adjustment
• Solid 6.5 kg cast-metal chassis provides complete vibration-free benchtop stability

Plan Achromatic Optics & Cool 3W LED Illumination

Plan Achromatic objectives eliminate spherical aberration and peripheral blur, keeping cellular membranes and nuclear structures crisp across the entire field of view. 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 cushion accidental contact, protecting both front glass elements and delicate specimen preparations.

Coaxial Focus Mechanics & Stage Translation

The double-layer mechanical stage provides smooth 75 x 40 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
