Kern OBE 109 Rechargeable Binocular Achromatic LED Gear

Description

Carried across remote agricultural crop stations and field ecology sites, the Kern OBE 109 Rechargeable Microscope provides cordless dry brightfield inspection. It features an internal rechargeable NiMH battery pack that runs the 3W LED base module without electrical cables. Powered by a finite 160 mm optical track, it provides 40x, 100x, and 200x dry magnification via four achromatic objectives: 4x/0.10, 10x/0.25, 20x/0.40, and an auxiliary low-power 4x/0.10 lens, keeping specimen screening completely free from immersion oils.

Transmitted light is focused through a sub-stage Abbe 1.25 NA condenser equipped with an iris diaphragm and filter slot. The 30-degree inclined binocular head carries paired widefield WF 10x/18 mm eyepieces with left-tube diopter adjustment across a 50 mm to 75 mm interpupillary span. The 125 x 115 mm mechanical stage provides 50 x 30 mm of drop-down coaxial XY translation, while coaxial coarse and fine focus knobs feature calibrated 2-micron division markings. Weighing 4.6 kg, the frame operates on internal battery power or multi-voltage 100-240V AC charging lines.

Key Features of Kern OBE 109 Rechargeable Microscope

A portable cordless laboratory binocular compound microscope featuring an all-dry objective configuration and internal rechargeable battery power. Combines 40x to 200x magnification with an Abbe 1.25 NA condenser, 3W LED lighting, and a double-layer mechanical stage.

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

All-Dry Achromatic Optics & Oil-Free Workflow

Eliminating immersion oil maintenance makes field inspections faster and cleaner when evaluating crop parasites, plant tissues, and seed samples. The 20x dry objective provides clear cellular magnification without sticky residues or lens wipe-downs. Achromatic multi-coated lenses preserve center-field clarity and natural color contrast across unstained botanical preparations.

Cordless Field Mobility & Coaxial Stage Mechanics

The internal rechargeable battery pack keeps the microscope running all day in remote field stations where electrical outlets are unavailable. The coaxial mechanical stage controls sit low to the table surface, giving technicians smooth two-axis slide tracking across a 50 x 30 mm area with resting forearms. Coaxial focus knobs operate with 2-micron precision, allowing delicate focal control on irregular plant cross-sections.

• Internal rechargeable batteries allow cordless microscopy anywhere in the field or lab
• All-dry objective configuration eliminates oil contamination and lens cleanup routines
• Low-position coaxial XY controls reduce wrist fatigue during high-volume sample rounds
