Levenhuk Rainbow 50L Amethyst Microscope is a perfect instrument for anyone to become acquainted with the mystery of the microworld. The wide range of available magnifications allows for studying a great number of various samples. For example, you can examine onion cells, find out if there are really live bacteria in yogurt, discover what kind of unseen microorganisms live in aquarium water, see what paper fibers look like and many other intriguing things. Levenhuk Rainbow 50L Amethyst Microscope stands out among regular biological models – the bright amethyst color makes observations even more fun! All of this makes this microscope a wonderful present for aspiring beginners.
Six degrees of magnification
The microscope comes with three objectives and additional Barlow lens, which doubles the magnification of each used objective. The microscope allows you to observe samples under 40x, 80x, 100x, 200x, 400x and even 800x magnifications out of the box!
The optics are made of quality highly transparent glass. For better transmission of light, the lenses are covered with multilayer coating, making produced images clear and sharp.
Bright LED illuminations
The microscope is equipped with two built-in LED illuminations. Lower illumination is used when observing transparent samples. With bottom light turned on you can find life in a drop of aquarium water or analyze the cellular structure of different plants. Top light is required for observing opaque objects; for example, you can examine the structure of a small stone’s surface or notice microscopic scratches invisible to the naked eye on metal surfaces. With two illuminations you also have an opportunity to observe semi-transparent samples – just turn both top and bottom lights on. Illumination brightness is adjustable, so you can easily change it if needed.
Ease of use
The microscope’s body is made of quality plastic; that’s why the instrument is lightweight and durable at the same time. The head is inclined at 45° so you can observe from a more comfortable position. It’s also rotatable 360° around its axis, which is especially convenient during group observations – the head can be easily rotated for the next participant to observe. For power, you can use either an electrical outlet or batteries.
Caution: Please refer to the specifications table for the correct mains voltage and never attempt to plug a 110V device into 220V outlet and vice versa without using a converter. Remember that mains voltage in the U.S. and Canada is 110V and 220-240V in most European countries.
Exciting experiments with microscope
The microscope comes with an experiment kit that allows you to conduct a number of enthralling experiments with the microscope. The kit includes prepared samples to try your new microscope right away, as well as instruments for making your own samples. A useful user guide also provided in the kit includes helpful information on microscope construction, tips on working with it, and a description of interesting experiments.
Case for storage and transportation
The microscope comes in a reliable and convenient plastic case. The case makes storing and transporting the instrument safe and easy – you can be sure that the microscope is protected from dust and impacts.
