KERN stereo microscope OSE-42
The robust and ergonomically designed microscope from Kern & Sohn is ideal for all professionals who expect comfort and precision in workshops, schools and vocational training. With its sturdy mechanical stand and integrated LED lighting, this device offers a high level of functionality. For analyzing components, metal samples or insects as well as for educational purposes in biology, materials science or quality control, it delivers razor-sharp images. Similar high-performance options such as the [KERN stereomicroscope OSE-45] also offer excellent optical properties, but may be less practical in terms of ergonomics and flexibility than the model presented here. So if you prefer a versatile device for different sample types, this stereomicroscope is the right choice.
Performance features and design
For even more comfortable working, the microscope is equipped with a 45° inclined binocular tube, which allows you to sit in an ergonomic position. Thanks to the Greenough optics, a three-dimensional image is created, which enables a realistic depth representation of the object being examined. A key feature is that the eyepieces are firmly anchored in the tube, which prevents both damage and loss. Due to this fixed construction, fewer errors occur during repeated installation and removal.
The diopter adjustment on both sides enables individual adjustments for both eyes. With an interpupillary distance of between 55 and 75 mm, the system is flexible enough for different users. Also worth mentioning is the interchangeable lens (2x / 4x), which, together with the wide field eyepieces (WF), achieves a magnification of up to 10x. This combination creates a large field of view of around 2 cm, which makes it much easier to view somewhat larger sample areas.The LED incident and transmitted light illumination, which can be switched on separately or together, are particularly noteworthy. This allows you to adapt the illumination concept precisely to your sample requirements. If required, the device can be used mobile with rechargeable batteries, making it an extremely flexible solution for everyday laboratory work or demonstrations in school environments.Key technical data

The stable mechanism of the stand guides the examination head precisely and withstands repeated vertical adjustment without deviation. The design also guarantees a high degree of stability when adjusting the focusing mechanism, which is a decisive advantage, especially with sensitive samples. Those who work at several locations benefit from the integrated handle and the low overall weight. The [KERN OZM-5] stereomicroscope offers a similar pleasure in mobile flexibility, but often does not have the same compactness.
Certifications and standards
The device was developed in accordance with modern standards and complies with the current DIN standards for minor deviations in optics. CE conformity ensures compliance with European health and safety requirements. This model therefore combines both operational safety and high optical precision, which is essential in professional quality assurance.
Application examples
- Inspection of circuit boards, PCBs and other electronic components for solder joint or component defects
.
- Animal and plant samples in biology, especially when observing fine structures such as insect wings or leaf surfaces.
- Training in schools and universities to deepen practical microscopy skills in chemistry, biology and materials science.
- Quality control in metal and plastics processing, where small surface structures or manufacturing defects need to be made visible.
- Inspection of seeds and soil in agricultural facilities to check for germination or pests.
FAQs
How can the lighting be optimally adjusted?
Thanks to LED incident and transmitted light, you can switch on both types of lighting independently. This allows you to optimize the illumination for a wide range of samples and avoid glare.
Can the microscope be operated wirelessly?
Yes, the device can be equipped with rechargeable batteries. Depending on the intensity of use, these provide around four hours of operating time.
Can the diopter compensation be adjusted individually?
Diopter rings on both sides enable precise corrections so that users with different visual acuity can also work very well with them.
Which magnifications can be used
The 2x / 4x objective lens and wide-field eyepieces allow you to achieve up to ten times magnification, enabling you to capture fine details in the three-dimensional image.
Is a range of accessories available
Additional eyepieces, external illumination units or alternative tripods are available on request. This allows the system to be expanded particularly flexibly.
Conclusion
The model described here offers a balanced combination of robust construction, flexible illumination and ergonomic design. Professional users in workshops, laboratories and teaching benefit from the high-precision mechanics and powerful optics. The possibility of battery operation and the integrated handle ensure uncomplicated mobility. If you are looking for a versatile device with remarkable image quality, the KERN OSE-42 stereomicroscope is the one for you.
