Bresser Junior Biolux SEL 40–1600x microscope with its extensive range of accessories offers an optimal introduction to microscopy. Unique to these models is the Barlow zoom system in the eyepiece socket: by means of a pull-out additional lens, the magnification can be continuously changed up to 2 times during visual observation, so that together with 3 objectives and 2 interchangeable wide-field eyepieces magnifications of 40x to 1600x can be achieved.
