KERN OLM 171 Metallurgical Inverted Microscope
The KERN OLM 171 Metallurgical Inverted Microscope has been specially developed for professional use in materials testing, material analysis and quality control. Thanks to its robust construction, high-precision optics and ergonomic design, this microscope enables reliable and efficient examination of opaque and solid samples. Compared to conventional light microscopes, it sets new standards with its large working distance and flexible usability - a clear advantage for laboratories and industrial users who demand the highest standards of image quality and ease of use.
Technological highlights for the highest demands
The inverted design makes the device ideal for examining thick, difficult-to-access samples, such as metallic surfaces, weld seams or fracture edges. Thanks to its stable base and innovative optics, the system remains vibration-free even during lengthy routine work and guarantees repeatable results. At its heart is the professional infinity optical system, which delivers brilliant, high-contrast images with high depth of field and clarity.

Other relevant features:
The ergonomic design of the Siedentopf tube effectively prevents fatigue during longer observation phases. Individualised settings can be made quickly. Another highlight is the integrated polarisation unit (consisting of an analyser and polariser), which enables targeted material investigations of reflection properties and structures. The adjustable incident light illumination ensures precise results even in demanding contrast investigations.
The large mechanical stage offers sufficient space for a wide variety of sample shapes and can be focused both coarsely and precisely with great sensitivity. A camera can be attached directly to the trinocular outlet for documentation or image analysis - ideal for laboratory documentation or training purposes.
