Kern OBE 104 Trinocular Achromatic 3W LED Lab Device

Description

Eliminating messy lens cleanup during live classroom demonstrations, the Kern OBE 104 Trinocular Microscope provides dry digital video capture. Powered by a finite 160 mm optical track, it delivers 40x, 100x, and 400x magnification via three dry achromatic objectives: 4x/0.10, 10x/0.25, and spring-loaded 40x/0.65, completely bypassing immersion oils. 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 widefield WF 10x/18 mm eyepieces.

Transmitted light is driven by a high-output 3W LED base module that produces cool, daylight-balanced white light without thermal specimen distortion. An Abbe 1.25 NA condenser features an adjustable iris diaphragm and filter slot, while the 125 x 115 mm mechanical stage provides 50 x 30 mm of drop-down coaxial XY translation. Built around a 4.8 kg cast-metal frame (320 x 180 x 360 mm), it includes coaxial coarse and fine focus knobs with 2-micron graduations on universal 100-240V AC power with an integrated electronic rotary dimmer.

Key Features of Kern OBE 104 Trinocular Microscope

A digital-ready educational trinocular biological compound microscope featuring an all-dry objective set, cool 3W LED illumination, and a dedicated camera port. Combines 40x to 400x magnification with an Abbe 1.25 NA condenser, double-layer mechanical stage, and 2-micron coaxial focus mechanics.

• Dedicated vertical photo port channel on top of head unit for digital camera integration
• 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
• Trinocular viewing head inclined at 30 degrees with paired widefield WF 10x/18 mm eyepieces
• Solid 4.8 kg cast-metal chassis provides complete vibration-free benchtop stability

Dry Achromatic Optics & Digital Video Output

Capping magnification at an all-dry 400x ceiling prevents sticky oil messes on shared classroom equipment while delivering the resolving power needed to inspect onion epidermis and blood smears. The vertical photo port accepts standard C-mount adapters, letting teachers project real-time microscopic video to classroom interactive boards while students observe through the eyepieces. Achromatic multi-coated lenses preserve natural color contrast across stained slide 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 50 x 30 mm coordinate translation via right-hand drop-down stalks, while the 2-micron fine-focus wheel allows precise focal plane isolation. The spring-loaded 40x objective protects slide cover slips from accidental mechanical strikes.

• Vertical photo port routes clean optical data to external digital video capture systems
• Dry 40x objective eliminates oil contamination and lens cleanup routines
• Forward-facing quadruple nosepiece with positive click-stops ensures smooth lens rotation
