Description
Introduce geology students to polarized light microscopy without cord clutter using the Optika B-150P-BRPL Polarizing Microscope. Powered by an internal rechargeable battery pack, this 3.5 kg portable workstation delivers 40x, 100x, and 400x magnification via three N-PLAN semi-planchromatic polarizing objectives: 4x, 10x, and a high-contrast 40x lens. The 30-degree inclined binocular head rotates 360 degrees, fitted with paired widefield WF 10x/18 mm eyepieces across an ergonomic viewing profile.
Transmitted illumination is supplied by a patented X-LED1 1W white LED system with a custom optical condensing lens, controlled by a manual dimmer scroll wheel on the base. The sub-stage houses an Abbe 1.25 NA condenser with an adjustable iris diaphragm and a rotatable polarizer filter, paired with a swing-out analyzer block beneath the head. The 120 mm circular stage rotates 360 degrees manually with a mechanical side-locking screw, supported by coaxial coarse and fine focus knobs with 2-micron graduations running on universal 100-240V AC charging power.
Key Features of Optika B-150P-BRPL Polarizing Microscope

- Height-adjustable Abbe 1.25 NA condenser equipped with an adjustable iris diaphragm
Transmitted Polarizing Optics & Crystal Birefringence
Analyzing sand grains, chemical crystals, and mineral thin sections requires polarized light to reveal pleochroism and interference colors. The sub-stage polarizer and overhead analyzer convert plain light into crossed-polarized waves, making birefringent mineral structures glow vividly against a dark background. N-PLAN objectives correct field curvature across the specimen field, keeping crystal boundaries sharp from center to perimeter.
Rechargeable Battery Freedom & Rotatable Stage Mechanics
Tangled power cables create tripping hazards when students move around geology lab tables. The internal rechargeable battery pack keeps the cool 1W LED running all day on a single charge, allowing seamless transport between classroom desks and field sorting benches. The 120 mm circular stage rotates smoothly by hand, letting students find crystal extinction positions easily before tightening the side lock screw.
- Internal rechargeable batteries allow cordless microscopy anywhere in the field or lab
- Rotatable circular stage allows quick identification of isotropic and anisotropic minerals
- Coaxial focus mechanics with 2-micron graduations provide delicate focal plane control
