Discovery offers a captivating combination of stories from science and technology, exploration, adventure, history, and deep behind-the-scenes insights of the people, places, and organizations that shape and share the world we live in. We are excited to present the series of optical devices produced by Levenhuk and supported by Discovery. <br> <br>See a quick comparison of the Discovery microscope series » The Levenhuk Discovery Nano is a classic monocular microscope (i.e. with an eyepiece) that enables exciting observations at 40 to 400x magnification. You can study already prepared sample carriers from the sets, and of course you can also make your very own sample carriers. This microscope is just the thing for the first encounters with the world on a very small scale, for the first simple scientific experiments at home. Also a great companion for biology lessons at school. The set contains everything you need to observe. Also the necessary accessories and the book ''''Invisible World'''' with knowledge to read and many colour illustrations. The optical system includes achromatic objectives and a wide-angle eyepiece. Since all lenses are made of first-class optical glass, the instrument delivers a sharp, high-contrast image. The microscope allows the observation of tiny things over the entire magnification range. The 40x magnification lens is equipped with the spring-loaded frame. The monocular head can be tilted 30°; this means that even longer observation sessions do not degenerate into uncomfortable contortions. There are retaining clips on the stage to fix the samples, as well as an iris diaphragm disc with six openings to regulate the brightness. The microscope offers dual LED illumination that illuminates the samples from above and below. This allows you to observe opaque and transparent samples equally well. The lighting is powered by standard batteries. We also include the book ''''Invisible World''''. This book with numerous color illustrations explains everything complicated in a simple way, for example the parts of the microscope and their functions, the appearance of bacteria and protozoans (primeval animals), what can be discovered in a drop of water and much more in simple language. In addition to the necessary theory, the book also describes interesting experiments that can be experienced in the comfort of your own home with the Levenhuk Discovery Nano microscope.
