Kern OBE 108 Binocular Achromatic 3W LED Lab Device

Description

Screen large tissue cross-sections and aquaculture parasites using the Kern OBE 108 Binocular Microscope. Powered by a finite 160 mm optical track, it provides 40x, 100x, and 200x dry magnification via four achromatic objectives: dual 4x/0.10 lenses, 10x/0.25, and 20x/0.40. Capping magnification at 200x makes it an ideal workhorse for inspecting macro tissue structures, fish gill scrapes, and botanical stem sections without needing oil immersion.

Transmitted light comes from an energy-efficient 3W LED base module focused through an Abbe 1.25 NA condenser equipped with an adjustable iris diaphragm and filter slot. The 30-degree inclined binocular head rotates 360 degrees for easy bench sharing, paired with widefield WF 10x/18 mm eyepieces with left-eye dioptric adjustment across a 50 mm to 75 mm interpupillary span. Built around a 4.5 kg cast-metal frame (320 x 180 x 360 mm), it features a 125 x 115 mm mechanical stage (50 x 30 mm XY travel) and coaxial focus knobs with 2-micron graduations on universal 100-240V AC power.

Key Features of Kern OBE 108 Binocular Microscope

An accessible biological binocular compound microscope configured specifically for macro tissue screening and veterinary student training. Combines 40x to 200x all-dry magnification with an Abbe 1.25 NA condenser, 3W LED illumination, and a double-layer mechanical stage.

• All-dry achromatic objective payload: dual 4x scanning lenses, 10x, and 20x magnification
• 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

All-Dry Achromatic Optics & Low-Power Screening

Many routine tissue audits and parasite screenings do not require high-power oil immersion. The OBE 108 focuses on clear macro and intermediate magnification, letting technicians inspect wide histological slices and aquatic parasite clusters without messy oil cleanup. The dual 4x objectives let you keep one low-power lens ready while rotating between 10x and 20x detail views, preserving sharp center-field contrast throughout your audit.

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 3W LED lamp provides a daylight-balanced continuous spectrum that renders biological stains with authentic color saturation without thermal distortion.

• Compact footprint frees up counter space on crowded veterinary and diagnostic benches
• 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
