The Optika B-382PL-ALC is a binocular brightfield microscope built for routine laboratory and teaching use. It carries N-PLAN objectives from 4x to 100x oil, covering 40x to 1000x total magnification. The exclusive X-LED3 illumination pairs with Automatic Light Control, keeping brightness stable when the objective or diaphragm changes. The double layer rackless stage and coaxial coarse and fine focusing give smooth handling during long sessions. It suits biology, botany, and general laboratory brightfield observation.
Optika B-382PL-ALC Binocular Brightfield Microscope
The Optika B-382PL-ALC is a binocular brightfield microscope from the B-380 series, built for routine laboratory and educational use. It combines N-PLAN objectives with the exclusive X-LED3 illumination system.
Automatic Light Control keeps brightness stable when the objective, diaphragm, or specimen changes, reducing manual adjustment during a session.
Automatic Light Control for Consistent Brightness
Once a brightness level is set, the B-382PL-ALC keeps it automatically when the objective is switched, the diaphragm is adjusted, or a new specimen is loaded.
N-PLAN Objectives for Routine Brightfield Work
The N-PLAN objective set covers 4x, 10x, 40x, and 100x oil/water immersion, all anti-fungus treated with a 45 mm parfocal distance.
The Abbe N.A. 1.25 condenser is focusable and centerable for consistent illumination across the field.
Rackless Double Layer Stage
The 150×139 mm double layer mechanical stage moves on a rackless, belt-driven mechanism with a 75×33 mm moving range and 0.1 mm vernier scale accuracy.
Coaxial Focusing with Limit Stop
Coarse and fine focusing share a coaxial control, with 25 mm coarse travel and 2 um fine resolution. An upper stop prevents contact between the objective and the specimen.
Ideal Applications
The B-382PL-ALC suits laboratories and schools that need dependable brightfield observation.
- Biology and botany sample observation
- Routine laboratory brightfield screening
- Educational and university teaching labs
- General cell and tissue observation
- Entry-level clinical and veterinary use
Choose the B-382PL-ALC when:
- You need a straightforward binocular brightfield microscope
