The KERN OZM-5 models are very robust and easy-to-use stereomicroscopes with double-zoom operation. Due to the nature, the column stand and the integrated, dimmable LED incident and transmitted light, these models are particularly flexible. All variants have adjustment options for diopters on both tubes. In addition, a trinocular model version is available, which allows the connection of a camera. These models are ideal for workplaces with a harsh working environment, such as training companies, workshops, and assembly and repair workplaces in the electronics industry. These models are also ideal for use in manufacturing and quality control, as well as in the biological laboratory and research field. The design of the optical system allows a large depth of field, with refocusing in the zoom magnification is required only to a minimum extent. In addition, it offers an exact resolution, an extra large field of view and is absolutely true to color. Due to the extra large working distance, these models offer maximum comfort through their large work surfaces. The variety of selectable lenses, eyepieces, universal stands and other accessories allows the use for all common applications of stereomicroscopy. A central feature of this variable and robust microscope series is the stable and precisely adjustable mechanism. This is underlined by the functional and ergonomic design.
