KERN OBN 135 transmitted light microscope
The KERN OBN 135 is an advanced transmitted light microscope that has been specially developed for demanding routine examinations in laboratories, research and industrial quality assurance. With modern infinity optics, flexible expansion options and ergonomic design, it stands out from comparable models thanks to its modular versatility and excellent image quality. In any professional environment, it guarantees reproducible and reliable analysis results that meet the highest standards of precision, comfort and future-proofing.
Precision and flexibility for professional microscopy
With its trinocular design and sophisticated range of functions, this microscope supports numerous microscopic procedures. The 5x objective turret, in combination with high-quality infinity plan objectives, ensures brilliant, high-contrast images across all magnifications - from an overview of samples to ultra-sharp detail at 100x magnification.
The continuously adjustable 3W LED illumination ensures homogeneous illumination and precise work even during long examinations. The ergonomic, mechanical cross table and precise coaxial focusing (coarse and fine adjustment up to 0.002 mm) enable comfortable and fatigue-free work.
Key technical features at a glance:
- Infinity optical system with fully coated plan objectives (4x, 10x, 20x, 40x, 100x)
- Trinocular tube for simultaneous observation and digital documentation
- 5-position objective turret for quick selection of different magnifications
- Precise, coaxial coarse and fine focus (minimum fine focus: 0.002 mm)
- Dimmable 3W LED transmitted light illumination with long service life
- High-quality Abbe condenser (NA 1.25), centred and with illumination field diaphragm
- Compact design: 390 x 200 x 395 mm (WxDxH)
The system can be easily supplemented with additional accessories such as phase contrast kits or a camera (via C-mount adapter). The modular design of the KERN OBN 135 allows for customised adaptation to a wide range of scientific and industrial requirements.
A special highlight is the integrated Köhler illumination, which enables maximum contrast values through precise control of the light field and aperture diaphragm. The standard scope of delivery also includes a robust dust cover for protection in everyday laboratory use.

FAQ - Frequently asked questions
Image quality at different magnifications
The robust infinity plan optics enable exceptional image sharpness and high contrast across all lens magnifications. Even sensitive cell structures and the smallest material defects are reliably and clearly displayed.
Digital image documentation and camera connection
Thanks to the trinocular tube, connecting a microscope camera is easy. With an optional C-mount adapter, digital camera systems can be seamlessly integrated, supporting professional documentation and live presentation.
Extension for phase, dark field or polarisation applications
Thanks to its modular design and wide range of available accessories (e.g. phase contrast sets, polarisation filters), the microscope can be upgraded at any time for more advanced examination procedures.
Maintenance and durability
The microscope is designed for long-term laboratory use. The LED illumination requires minimal maintenance, while the optical and mechanical components are effectively protected by regular cleaning and the dust cover.
Comfort and ergonomics for prolonged use
Ergonomically positioned controls, high focusing accuracy and a generous cross table ensure comfortable handling, especially during prolonged routine work.
