Kern OPO 185 Trinocular Polarization Dual Halogen Optic

Description

Analyze opaque mineral ores and geological thin sections using the Kern OPO 185 Trinocular Polarizing Microscope universal research workstation. Built for dual-path materials science, it features two independent 12V/100W halogen illuminators powered by standalone external digital controllers: an upper EPI-reflected housing with field and aperture diaphragms for opaque alloys, and a sub-stage transmitted lamp for petrographic thin sections. Powered by an infinity-corrected IOS optical system, it delivers 40x, 100x, 200x, 400x, and 600x magnification via five stress-free Infinity Plan objectives: 4x, 10x, 20x, spring-loaded 40x, and 60x.

A 30-degree inclined trinocular head incorporates a multi-channel optical splitter and a vertical photo tube port for digital camera archiving, paired with extra-widefield high-eyepoint HWF 10x/22 mm eyepieces with an integrated crosshair reticle. The 160 mm circular stage rotates 360 degrees continuously with 1-degree increments and a nonius vernier accurate to 6 arc-minutes, equipped with an attachable mechanical stage tool. The intermediate polarizing housing includes a focusable Bertrand lens system and test wave sliders across a massive 14.5 kg cast chassis (320 x 260 x 540 mm) with 1-micron coaxial fine focus graduations.

Key Features of Kern OPO 185 Trinocular Polarizing Microscope

A flagship combination upright metallurgical and geological polarizing research microscope featuring dual 100W halogen illumination systems. Combines five stress-free Infinity Plan objectives with reflected and transmitted light paths, a 160 mm rotating vernier stage, Bertrand lens, and 1-micron focus mechanics.

• Stress-free Infinity Plan objectives: 4x, 10x, 20x, spring-loaded 40x, and high-dry 60x
• Circular 160 mm stage with 360-degree rotation, 1-degree scale, and 6 arc-minute vernier
• Includes attachable mechanical stage tool for precise two-axis petrographic slide translation
• Integrated Bertrand lens slider block for orthoscopic and conoscopic crystal analysis
• Top-mounted straight vertical trinocular photo tube port for digital C-mount camera integration
• Coaxial coarse and fine focus drive with calibrated 1-micrometer (0.001 mm) fine steps

Dual 100W Halogen Illumination & Stress-Free Optics

Dark ore minerals and dense rock thin sections absorb vast amounts of light, causing weak reflections under standard 30W lamps. The dual 100W halogen light engines flood both light paths with intense photon density, cutting through dense crystal lattices and dark carbon fibers. The stress-free Infinity Plan objectives eliminate residual glass strain, delivering pure black extinction under crossed polarizers so petrographers can accurately identify anisotropic minerals.

Conoscopic Bertrand Analysis & 1-Micron Focus Precision

Swapping between standard orthoscopic viewing and conoscopic interference figures takes seconds: slide the centerable Bertrand lens into the light path to observe isogyres and melatopes directly through the HWF 10x/22 mm crosshair eyepieces. The 160 mm stage features dual centering screws to align rotational centers with the optical axis, while the vernier reads down to 6 arc-minutes for precise angular logging. The coaxial focus drive moves in 1-micron steps, giving technicians delicate control over polished metal surfaces.

• Dual 100W halogen illuminators provide maximum light penetration for opaque and translucent media
• Integrated Bertrand lens provides instant toggling between orthoscopic and conoscopic views
• Precision 6 arc-minute vernier stage enables accurate crystal extinction angle calculations
