The Optika B-383PHi is a trinocular phase contrast microscope built for laboratories that need reliable observation of unstained, transparent specimens with camera documentation. It carries IOS W-PLAN PH objectives from 10x to 100x oil and a 5-position condenser covering brightfield, phase contrast, and darkfield on dry objectives. The exclusive X-LED3 illumination gives consistent brightness across the objective range. The rackless double layer stage and coaxial focusing keep daily handling smooth. It suits microbiology, cytology, and routine laboratory work.
Optika B-383PHi Trinocular Phase Contrast Microscope
The Optika B-383PHi is a trinocular phase contrast microscope from the B-380 series, built for routine laboratory work with unstained specimens and camera-based documentation.
IOS infinity-corrected W-PLAN PH objectives pair with a 5-position rotating condenser for brightfield, phase contrast, and darkfield observation.
IOS W-PLAN PH Objectives for Phase Contrast Work
The objective set covers 10x, 20x, 40x, and 100x oil magnifications, plan achromatic corrected with a DIN 45 parfocal distance.
5-Position Condenser for Multiple Techniques
The condenser gives brightfield, three phase contrast settings, and a darkfield position for dry objectives, all on the same stand.
Rackless Double Layer Stage
The 233×147 mm double layer mechanical stage uses a belt-driven, rackless mechanism with a 78×54 mm X-Y 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-383PHi suits laboratories that regularly examine transparent, unstained specimens.
- 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-383PHi when:
- You need phase contrast for unstained, transparent specimens
- You need infinity-corrected IOS optics on a trinocular stand
- You want camera documentation alongside visual observation
- You process routine laboratory samples with mixed brightfield and phase contrast needs
Optika Value Proposition
The Optika B-383PHi combines IOS infinity-corrected optics with a rackless mechanical stage on a trinocular stand, backed by Optika 10-year mechanical and optical warranty plus lifetime X-LED warranty.
