Description

Levenhuk Rainbow 50L Microscope is a great gift for anyone interested in biology and science. The instrument allows for observing and studying familiar objects of our surrounding environment under 40x, 80x, 100x, 200x, 400x and even 800x magnification! With this microscope you can find out how plants, animals and humans are structured; take a look at how microscopic organisms, usually hidden from us, live in their own micro-universe; and, of course, conduct a number of exciting experiments. The kit includes everything a novice researcher might need – in the box you will find prepared microscope slides to observe right away as well as tools allowing you to create your own slides.

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.

Customer service:
Yes, Levenhuk Rainbow 50L model allows you to examine dust mites, a drop of blood, and organisms in liquids.
Paul Carson (2016.05.17)
Hello! What additional accessories should I buy to this model? Actually I'm choosing between this microscope and Levenhuk 320... The only thing that makes me hesitate is the absence of upper illumination in 320 model - that means I won't be able to observe opaque objects, right? Or a simple table lamp will do the job?
Customer service:
Levenhuk 320 Biological Microscope will give you a much better image. But yes, it doesn't allow for observing opaque samples. Both microscopes can be equipped with a digital camera (https://www.levenhuk.com/catalogue/accessories/microscope-accessories/microscope-digital-cameras/ ) and an eyepiece (https://www.levenhuk.com/catalogue/accessories/eyepieces-for-microscopes/ ).
