Kern OBN 132 Trinocular Infinity Plan Halogen Optic

Description

Eliminate color rendering distortion during clinical diagnostic screenings using the Kern OBN 132 Halogen Microscope. It features a full Köhler transmitted illumination system powered by an adjustable 6V/20W halogen sub-stage module, producing an authentic continuous light spectrum that defines cellular boundaries cleanly. Powered by an infinity-corrected optical train with true flat-field alignment, it delivers 40x, 100x, 200x, 400x, and 1000x magnification through five Plan Achromatic objectives: 4x/0.10, 10x/0.25, 20x/0.40, spring-loaded 40x/0.65, and spring-loaded 100x/1.25 oil immersion.

A swing-out Abbe condenser (NA 0.9/1.25) pairs with a field diaphragm to provide centered, glare-free illumination from 4x macro scans up to 1000x oil immersion. The 30-degree inclined trinocular head incorporates a vertical 23.2 mm photo port with an internal beam splitter, paired with widefield high-eyepoint WF 10x/20 mm eyepieces. The oversized 175 x 145 mm mechanical stage features a scratch-proof ceramic coating and low-drop coaxial XY controls (78 x 55 mm travel). Coaxial coarse and fine focus knobs feature calibrated 2-micron fine division markings across a 9.0 kg cast-metal frame running on universal 100-240V AC power.

Key Features of Kern OBN 132 Halogen Microscope

A research-grade quintuple-nosepiece biological compound microscope featuring 20W quartz halogen Köhler illumination and a vertical camera port. Combines five Infinity Plan objectives with a ceramic-coated stage, swing-out Abbe condenser, and 2-micron focus mechanics for clinical pathology labs.

• Solid 9.0 kg cast-metal chassis provides complete vibration-free benchtop stability

Warm Halogen Spectrum & Infinity Plan 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 20 mm field of view.

Ceramic Stage Durability & Trinocular Camera Output

The oversized ceramic-coated stage resists scratches from abrasive slide edges and harsh staining solvents, while low-drop coaxial XY control stalks keep hand movements relaxed during extended screenings. The vertical photo port routes clean optical data to external digital C-mount cameras, letting pathology teams capture publication-grade photomicrographs while actively viewing through the oculars.

• Warm halogen light engine provides stable, continuous-spectrum illumination for cytology
• Reversed five-position nosepiece keeps slide placement unobstructed and open
• Vertical camera channel allows simultaneous eyepiece viewing and digital documentation
