Kern OBE 102 Binocular Achromatic 3W LED Lab Device

Description

Delivering clean 40x to 400x dry brightfield magnification, the Kern OBE 102 Binocular Microscope handles routine veterinary checks and medical student lab coursework without oil immersion. Operating on a finite 160 mm optical pathway, it features three achromatic objectives: 4x/0.10, 10x/0.25, and spring-loaded 40x/0.65. Anti-fungus treated lenses provide crisp center resolution across the 18 mm field of view, keeping stained smear structures and parasite eggs clearly defined.

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. An Abbe 1.25 NA condenser features an integrated iris diaphragm and filter slot for precise contrast tuning on wet mounts. The 30-degree inclined binocular head rotates 360 degrees, fitted with paired widefield WF 10x/18 mm eyepieces across an adjustable 50 mm to 75 mm interpupillary span. The 125 x 115 mm mechanical stage provides 50 x 30 mm of coaxial XY travel, while coaxial focus knobs feature 2-micron graduations across a 4.5 kg cast chassis powered by universal 100-240V AC power.

Key Features of Kern OBE 102 Binocular Microscope

A standard clinical practice and educational binocular compound microscope featuring an all-dry achromatic objective set and cool 3W LED illumination. Combines 40x to 400x magnification with an Abbe 1.25 NA condenser, double-layer mechanical stage, and 2-micron coaxial focusing.

• Dry achromatic finite 160 mm objectives: 4x, 10x, and spring-loaded 40x (no oil required)
• Revolving quadruple forward-facing objective turret with smooth mechanical click-stops
• High-output transmitted 3W LED white illumination module with continuous rotary dimmer
• Height-adjustable Abbe 1.25 NA condenser equipped with an adjustable iris diaphragm
• Double-layer 125 x 115 mm mechanical stage with 50 x 30 mm coaxial XY travel controls
• Coaxial coarse and fine focus drive with calibrated 2-micrometer fine division markings
• Binocular viewing head inclined at 30 degrees with 50 mm to 75 mm eye spacing
• Solid 4.5 kg cast-metal chassis provides complete vibration-free benchtop stability

Achromatic Optical System & All-Dry Workflow

Eliminating immersion oil cleanup saves valuable instruction time in educational labs and outpatient clinics. The dry 40x objective provides crisp 400x cellular resolution on plant tissues, protozoa, and urinary sediment without sticky residues. Achromatic multi-coated lenses preserve center-field clarity and natural color contrast, while the spring-loaded 40x objective protects slide cover slips from accidental mechanical strikes.

Coaxial Focus Mechanics & Stage Translation

The double-layer mechanical stage provides smooth 50 x 30 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 forward-facing quadruple nosepiece features tactile click-stops for positive lens centering.

• Compact footprint frees up counter space on crowded veterinary and diagnostic benches
• Abbe condenser iris diaphragm allows fine contrast tuning across all objective powers
• Dry 40x objective eliminates oil contamination and lens cleanup routines
