Working Purpose
Biological Laboratory Observation
The KCX-199 Advanced Phase Contrast Microscope is designed for examining biological specimens and prepared laboratory slides.
Its infinity-corrected optics and multiple objective lenses support observation of suitable cells, tissues and microscopic structures.
Scientific Research Laboratories
Research laboratories can use the KCX-199 for routine biological microscopy and laboratory investigations.
Its mechanical stage, precision focusing controls and adjustable illumination provide a practical configuration for specimen examination.
Educational Institutions and Universities
Schools, colleges, universities and scientific training centers can use the microscope for biological practical sessions, laboratory demonstrations and microscopy education.
Cell Biology Research
The microscope can support examination of suitable cell specimens and prepared slides.
Phase-contrast observation of transparent, unstained cells requires compatible phase objectives and a matching phase condenser or phase annulus system.
Microbiological Observation
The KCX-199 can be used for observing appropriately prepared and stained microbial specimens.
Its 40X and 100X objectives support high-magnification examination within the capabilities of conventional optical microscopy.
Pathology and Laboratory Training
The microscope can support educational observation of prepared tissue sections and pathological teaching slides.
Any use for clinical diagnosis requires appropriate validation and compliance with applicable requirements.
Digital Microscope Imaging
The trinocular observation head can support integration with compatible digital cameras through suitable adapters.
This allows microscope images to be captured or displayed digitally when the required imaging accessories are installed.
Pharmaceutical Research Laboratories
Pharmaceutical research and educational laboratories can use the microscope for suitable specimen observation, laboratory training and routine visual examination.
Scientific Demonstrations
The microscope can be used for classroom teaching, laboratory workshops and technical training involving optical magnification, specimen focusing and biological observation.
Working Principle
The Advanced Phase Contrast Microscope KCX-199 operates using compound optical magnification through an infinity-corrected optical system.
A prepared specimen is placed on the mechanical stage and positioned within the optical path.
Light from the adjustable 3.5W LED illumination system passes through the condenser and specimen before entering the selected objective lens.
The semi-plan infinity objective forms an optical image that is processed through the microscope's infinity-corrected optical system and viewed through the WF10X eyepieces.
The coaxial coarse and fine focusing controls allow users to adjust image sharpness, while the mechanical stage enables controlled specimen movement.
Phase Contrast Working Principle
Phase-contrast microscopy converts phase differences caused by variations in specimen thickness and refractive index into visible differences in image brightness.
In a correctly configured phase-contrast system, an annular diaphragm in the condenser produces a hollow cone of illumination. The objective's phase plate modifies the phase relationship between direct and specimen-diffracted light.
Interference between these light components produces contrast, allowing suitable transparent specimens to be observed without conventional staining.
Important: The supplied KCX-199 specifications list an Abbe condenser and semi-plan objectives but do not explicitly identify a phase annulus condenser or phase-contrast objectives. These components must be confirmed before claiming that the supplied configuration performs phase-contrast observation.
Optical Magnification Combinations
| Objective Lens | Eyepiece | Total Magnification |
|---|---|---|
| 4X Semi-Plan Infinity | 10X | 40X |
| 10X Semi-Plan Infinity | 10X | 100X |
| 40X Semi-Plan Infinity (SL) | 10X | 400X |
| 100X Semi-Plan Infinity Oil (SL) | 10X | 1000X |
Microscope Compatibility and Usage
The KCX-199 Advanced Phase Contrast Microscope is suitable for observation of compatible prepared biological slides and laboratory specimens.
It can be used in universities, research laboratories, biological laboratories, scientific training centers and educational institutions.
The trinocular observation head can support compatible digital imaging accessories, subject to the appropriate camera adapter and optical configuration.
For routine observation, users should select the appropriate objective lens, adjust LED illumination and use the coarse and fine focusing controls to obtain a clear specimen image.
The 100X oil immersion objective should be used with suitable immersion oil according to the microscope's operating instructions.
Phase-contrast operation requires confirmation of the appropriate phase objectives and matching condenser components.
