The Optika B-383PH is a trinocular phase contrast microscope with N-PLAN and W-PLAN PH finite objectives, built for routine laboratories that need phase contrast without infinity optics. The condenser covers brightfield, phase contrast at 10x, 20x, 40x, and 100x, plus a darkfield position for dry objectives. X-LED3 illumination gives consistent brightness across the objective range. The rackless stage and coaxial focusing keep daily handling smooth. It suits microbiology and general laboratory phase contrast work.
Optika B-383PH Trinocular Phase Contrast Microscope
The Optika B-383PH is a trinocular phase contrast microscope from the B-380 series, built around N-PLAN and W-PLAN PH finite objectives for routine laboratory work with unstained specimens.
The multiple position condenser gives brightfield, three phase contrast settings, and a darkfield position for dry objectives on the same stand.
N-PLAN and W-PLAN PH Finite Objectives
The objective set combines an N-PLAN 4x overview objective with W-PLAN PH 10x, 40x, and 100x oil objectives, all anti-fungus treated with a 45 mm parfocal distance.
Multiple Position Condenser
The condenser covers brightfield, phase contrast at 10x/20x, 40x, and 100x, and a darkfield position for dry objectives, all switchable on the same stand.
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.
Trinocular Head for Documentation
The trinocular head adds a camera port for photographic or digital documentation alongside visual observation.
Ideal Applications
The B-383PH suits laboratories that need phase contrast on a finite optics platform.
- Living cell and microorganism observation
- Microbiology and cytology screening
- Educational and university laboratory use
- Routine phase contrast diagnostics
- Camera-based documentation of phase contrast images
Choose the B-383PH when:
- You need phase contrast for unstained, transparent specimens
- You want an entry point into phase contrast without IOS infinity optics
- You want camera documentation on a trinocular stand
- You process routine laboratory samples with mixed brightfield and phase contrast needs
Optika Value Proposition
The Optika B-383PH combines N-PLAN and W-PLAN PH finite optics with a rackless mechanical stage on a trinocular stand, backed by Optika 10-year mechanical and optical warranty plus lifetime X-LED warranty.
