KERN OZL 445 stereo zoom microscope
The KERN OZL 445 stereo zoom microscope from Kern & Sohn is a professional solution for demanding tasks in laboratories, industrial manufacturing and quality assurance. Thanks to its high-quality Greenough optical system and flexible, stepless zoom function, the device impresses with exceptional image quality and maximum detail accuracy. Especially in the field of inspection, testing and documentation, it stands out from many competitors thanks to its ergonomic design, independent LED illumination and modular construction. The combination of precision, stability and versatility makes this microscope ideal for researchers, technicians and testing managers who are looking for uncompromising reliability.
During the development of the OZL 445, great importance was attached to simplifying complex structures and processes. The powerful Greenough optical system delivers lifelike, vivid images even of fine structural differences - a decisive criterion in quality control, bioanalytical examinations or detailed inspections in electronics manufacturing.
The stepless zoom function from 7.5x to 36x allows smooth switching between overview and detailed images without the need to change lenses. An individually adjustable eye relief of 55-75 mm and the ergonomically inclined (45°) and 360° rotatable tube ensure fatigue-free and flexible working, even during long sessions. These features are particularly valuable for teams that need to visualise and evaluate together from different angles.
The microscope is equipped with separately dimmable LED reflected and transmitted light illumination. State-of-the-art LED technology enables precisely controllable illumination of almost any sample - whether opaque material in technical testing or transparent biological structures. The robust column stand and compact format (230 x 235 x 360 mm) ensure secure stability and leave room for even larger samples or workpieces. With a net weight of only 4.31 kg, the device remains easy to transport and flexible in use.

Specific practical applications
The microscope meets the highest requirements in numerous fields of application, including:
- IVF laboratories: Precise control and selection of eggs and embryos during in vitro fertilisation, e.g. using buffer solutions and culture media.
- Quality control & material testing: Inspection of surface defects in metallurgy, examination of polymer structures, detection of cracks or inclusions.
- Electronics manufacturing: Repair and assembly of printed circuit boards and other electronic assemblies, e.g. analysis of faulty solder joints by means of optical inspection.
- Zoology and tissue preparation: Fine section preparations, e.g. tissue structures, insects or plant samples for research documentation.
- Detection of parasites: Analysis of biological preparations in veterinary medicine or biological research.
- Agriculture: Examination of seeds, kernels or plant structures to determine quality.
With the generous working distance and sophisticated lighting, even larger samples such as mechanical components, biological preparations or electronic components can be viewed efficiently and in great detail.
FAQs
How can the LED lighting be optimally adjusted?
The independent dimming function for reflected and transmitted light allows the light intensity to be adjusted as required. For coarsely structured samples, reflected light can be used to highlight surfaces, while transmitted light provides the best contrast for transparent samples such as cell structures or thin sections.
Is the OZL 445 compatible with other accessories?
Yes, Kern & Sohn offers a comprehensive range of accessories such as additional eyepieces, attachment lenses, special lighting units and universally compatible stands to meet individual or project-specific requirements.
For which types of samples is the device particularly suitable?
The device is particularly suitable for spatial and lightly structured samples such as biological preparations (cells, insects), industrial materials (plastics, metals), electronic components (circuit boards) or plant tissue.
Is the microscope ergonomically designed for long-term use?
The 45° tilt of the tube, the easy adjustability of the interpupillary distance and the vibration-free stand enable comfortable and safe use even over longer periods of time.
What certifications does the microscope have?
The microscope complies with both CE directives and relevant DIN standards for laboratory and analytical equipment, guaranteeing maximum reliability and safety in a professional environment.
Conclusion
The KERN OZL 445 stereo zoom microscope combines innovative optics, flexible illumination and versatile modular design to create a robust, user-friendly precision instrument.
