Description Discovery Channel informs, entertains and inspires audiences around the globe about the world in all its wonders, diversity and magic. Discovery offers millions of people the opportunity to discover and satisfy their curiosity. 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>Watch a quick comparison of the Discovery microscope series » Our Levenhuk Discovery Femto Polar is a classic monocular microscope that allows for very detailed observations of the tiny microworld in transmitted light and reflected light at magnifications of 40 to 400 times. They can study the cell structure of insects or plants, look at the diverse life in a drop of water or protozoan (primeval animals) and endless more. The microscope is also ideal for simple biological experiments at school. An informative book about the big world in miniature is also included. This means that you can really get started with microscopy right from the start and find countless exciting suggestions. Achromatic optics ensure a sharp and detailed image of your samples. The rotating head of the instrument (the revolver) is equipped with three objectives: 4x, 10x and 40x magnification, the latter eyepiece is spring-mounted. The wide-angle eyepiece provides a wide field of view at 10x magnification. The monocular head is angled by 45 °, thus ensuring a much more comfortable view through the eyepiece even during longer observations. In addition, the head can be rotated horizontally 360 °, as if made for group experiments. This allows other observers to simply turn their heads towards them without having to move the entire device. The microscope is equipped with separate knobs for coarse and fine adjustment (coarse drive and fine adjustment), so you can focus quickly and yet extremely sensitively. The illumination system consists of LEDs above and below the stage, which can be adjusted in brightness. The light from the lower lighting passes through a window cover, which also contributes to brightness control. For power supply, the device is satisfied with batteries (not included) or a power supply. Clips on the stage ensure that your samples stay in place. The book The Invisible World is a fascinating addition to your microscope. This book reveals the secrets of the microworld and shows you scientific experiments that you can experience for yourself. It is written in an easy-to-understand language, and there are many illustrations. You will learn a lot about the history and functioning of a microscope, in addition to numerous small experiments that you can perform at home with the Levenhuk Discovery Femto Polar.
