Kern OBF 132 Trinocular Plan Halogen Laboratory Gear

Description

Document stained histological sections under warm halogen lighting with the Kern OBF 132 Trinocular Microscope. Powered by a finite 160 mm optical system, it delivers 40x, 100x, 400x, and 1000x magnification via four Plan Achromatic objectives: 4x/0.10, 10x/0.25, spring-loaded 40x/0.65, and spring-loaded 100x/1.25 oil immersion. An integrated vertical 23.2 mm photo port on the 30-degree inclined trinocular head allows simultaneous digital camera capture while viewing through high-eyepoint WF 10x/18 mm eyepieces.

Transmitted illumination is supplied by an adjustable 6V/20W halogen sub-stage module focused through a height-adjustable Abbe 1.25 NA condenser with an iris diaphragm and filter slot. The 145 x 130 mm double-layer mechanical stage provides 75 x 40 mm of low-drop coaxial XY travel, while coaxial coarse and fine focus knobs feature calibrated 2-micron fine division markings. Built on a 6.8 kg cast-metal frame (395 x 200 x 380 mm), it incorporates a continuous electronic dimmer dial on the side panel, operating on universal 100-240V AC power with an internal transformer block.

Key Features of Kern OBF 132 Trinocular Microscope

A clinical and laboratory trinocular biological compound microscope featuring Plan Achromatic flat-field optics, warm 20W halogen 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 6.8 kg cast-metal chassis provides complete vibration-free benchtop stability

Warm Halogen Illumination & Plan Flat-Field Optics

Halogen lamps produce a continuous, high-CRI light spectrum that reveals subtle color differences in zoological cuts, stained histological sections, and cytology smears that look washed out under cold LEDs. The 20W halogen lamp provides a warm, high-CRI continuous spectrum that brings out true natural absorption colors across tissue sections. Plan Achromatic objectives eliminate spherical curvature and edge blur, keeping tissue margins crisp across the entire field of view.

Trinocular Video Output & Coaxial Stage Mechanics

The top-mounted vertical photo tube routes optical data directly to digital C-mount cameras, letting pathology teams capture publication-grade photomicrographs while actively viewing through the oculars. The double-layer mechanical stage provides smooth 75 x 40 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
• Warm halogen light engine provides stable, continuous-spectrum illumination for cytology
• Reversed quadruple nosepiece leaves the stage completely open for rapid slide swaps
