The KERN OZS-5 models are highly professional, very robust but easy-to-use stereomicroscopes with double-sided zoom function. Due to the nature, the column stand and the integrated, dimmable LED incident and transmitted light, these models are particularly flexible. All versions have diopter adjustment on both tubes and are delivered with an adapter to allow the connection of a camera. The parallel optical system allows fatigue-free working of the eyes and offers a great depth of field. Also, the refocusing in the zoom magnification is only necessary to a small extent. In addition, it offers an exact resolution, an extra large field of view and is absolutely true to color. These models are ideal for quality control, assembly and repair workstations in the electronics and semiconductor industries, as well as in biological laboratory and research applications. But even at workplaces with a harsh working environment, such as training companies, workshops and in manufacturing, these models are also ideal to use. 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 and professional 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
