Kern OBF 122 Binocular Plan Halogen Laboratory Gear

Description

Resolve fine histological cell margins through the Kern OBF 122 Binocular Microscope with flat-field Plan optics and warm halogen lighting. Powered by a finite 160 mm optical system, 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. Plan Achromatic optical correction eliminates spherical curvature across the field of view, keeping stained cell structures crisp from center to perimeter.

Transmitted illumination is supplied by an adjustable 6V/20W halogen sub-stage module focused through a height-adjustable Abbe 1.25 NA condenser equipped with an iris diaphragm, focus adjustment rack mechanics, and a filter slot. 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 low-drop coaxial XY travel, while coaxial coarse and fine focus knobs feature calibrated 2-micron fine division markings across a 6.6 kg cast chassis running on universal 100-240V AC power.

Key Features of Kern OBF 122 Binocular Microscope

An advanced clinical and laboratory brightfield binocular compound microscope featuring Plan Achromatic flat-field optics and warm 20W halogen illumination. Combines 40x to 1000x magnification with an Abbe 1.25 NA condenser, double-layer mechanical stage, and 2-micron coaxial focusing.

• Solid 6.6 kg cast-metal chassis provides complete vibration-free benchtop stability

Warm Halogen Illumination & Plan Flat-Field Optics

Halogen lamps produce a continuous, high-CRI light spectrum that reveals subtle color differences in zoological cuts, stained histological sections, and cytology smears that look washed out under cold LEDs. The 20W halogen lamp provides a warm, high-CRI continuous spectrum that brings out true natural absorption colors across tissue sections. Plan Achromatic objectives eliminate spherical curvature and edge blur, keeping tissue margins crisp across the entire field of view.

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.

• Plan Achromatic objectives provide flat-field resolution across the full field of view
• 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
