Endoscopic Zoom Lens from Berliner Glas

As an important part of an endoscopic camera, the zoom lens quality has great influence on the performance of the overall system. By using zoom lenses, endoscopic image magnification is accomplished that is comparable to microscopic examination. For endoscopes, zoom lens systems are usually made of two or three lenses which are shifted in axial direction to vary the focal length in order to enlarge objects in the field of view.

With its extensive experience in design and manufacturing of lenses and zoom lenses, Berliner Glas Medical Applications meets the needs of its customers in medical technologies and continually monitors new trends in product- and manufacturing technologies in this market. Berliner Glas zoom lens systems are designed to comprise high resolution (full HD), shock resistance, light weight, small (micro) dimensions and autoclavability, which have a high priority in medical technology. Berliner Glas meets this demand by guaranteeing at least 500 autoclave cycles for opto-electro-mechanical assemblies.

As an OEM manufacturer, Berliner Glas has extensive expertise in designing both optical and mechanical interfaces to integrate with the customer’s exisiting endoscope and camera systems. With highly developed engineering in optical design, systems in full HD (1080×1920 pixels) are possible.
Incremental shifting or continuous shifting between the desired focal lengths can be accomplished with either a mechanical or an electromechanical (motor) shift. Any desired lengths of travel or focal lengths can be designed according to the customer’s demands or to the endoscopic standard. The dimensions can be implemented for both tip-cameras and conventional cameras at the proximal end of the endoscope.
