Kern OBL 137 Trinocular Infinity E-Plan 3W LED Tool

Description

Capture high-resolution digital slide records and train medical technicians using the Kern OBL 137 LED Microscope. Powered by an infinity-corrected optical pathway, it delivers 40x, 100x, 400x, and 1000x magnification via four Infinity E-Plan objectives: 4x/0.10, 10x/0.25, spring-loaded 40x/0.65, and spring-loaded 100x/1.25 oil immersion. A dedicated vertical 23.2 mm photo port on the 30-degree inclined trinocular head routes optical data directly to digital C-mount cameras while maintaining binocular viewing through high-eyepoint WF 10x/20 mm eyepieces.

Transmitted light is driven by a high-output 3W LED sub-stage module that produces uniform, cool white illumination without thermal specimen drift. A height-adjustable Abbe 1.25 NA condenser features an integrated iris diaphragm and filter slot for precise contrast tuning on wet mounts. The 145 x 130 mm double-layer mechanical stage provides 76 x 52 mm of coaxial XY travel via low-positioned right-hand stalks, while coaxial coarse and fine focus knobs feature calibrated 2-micron graduations across a 6.7 kg cast-metal frame running on universal 100-240V AC power.

Key Features of Kern OBL 137 LED Microscope

A professional laboratory trinocular biological compound microscope featuring Infinity E-Plan optics, cool 3W LED illumination, and a dedicated camera port. Combines 40x to 1000x magnification with an Abbe 1.25 NA condenser, double-layer mechanical stage, and 2-micron coaxial focus drive.

• Solid 6.7 kg cast-metal chassis provides complete vibration-free benchtop stability

Infinity E-Plan Optics & Cool 3W LED Illumination

Infinity-corrected E-Plan optics eliminate spherical aberration and color fringing, keeping stained plant histology and cellular smears crisp across the entire 20 mm 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.

Trinocular Camera Routing & Stage Translation

The top-mounted vertical photo tube routes clean optical data to external digital C-mount cameras, letting laboratory teams record high-resolution photomicrographs while actively viewing through the oculars. The double-layer mechanical stage provides smooth 76 x 52 mm coordinate translation via right-hand drop-down stalks, while the 2-micron fine-focus wheel allows precise focal plane isolation under 1000x oil immersion.

• Vertical photo port routes clean optical data to external digital video capture systems
• Cool-running 3W LED light source prevents thermal expansion in living specimens
• Reversed quadruple nosepiece leaves the stage completely open for rapid slide swaps
