Levenhuk Rainbow 50L PLUS Amethyst Microscope
Stylish, colorful, modern microscope for amateur biologists. Experiment kit included. Magnification: 64–1280x.
Whether it is biology or chemistry classes at school, laboratory research in some medical institution, or independent amateur studies at home – everything will become much more exciting with Levenhuk Rainbow 50L PLUS Amethyst Microscope! Beginners will definitely like our experiment kit that contains lots of interesting microscope samples, while experienced users will appreciate its superior optics, ergonomic design, and reliable body. The microscope’s colorful, original design makes it a wonderful present for anyone interested in biology.
Three objectives allow you to obtain 64x, 160x, and 640x magnification. 40xs objective lens has a special spring-loaded mechanism. While focusing, you may accidently touch the observed sample with the objective lens. But the spring-loaded lens will retract a little, preventing any possible damage. The kit also includes 2x Barlow lens which doubles the magnification of any given objective lens. The basic kit allows you to achieve 1280x magnification power!
The lenses are made of high-quality optical glass coated with special anti-reflective coating. The produced images will always be sharp, contrast, and crystal-clear.
Universal LED illumination system
The microscope is equipped with two bright LED illuminators. To observe transparent samples such as cat hair or tiny crustaceans, use lower illumination. Upper illumination is used for opaque objects - paper fiber, coins, and many other interesting things. Semi-transparent objects are better seen when you use both upper and lower illumination. The adjustable brightness allows you to choose the optimal amount of light for each sample.
The microscope is distinguished by its modern ergonomic design. The reliable metal body of the microscope ensures its long service life. The 45-degrees inclined monocular head allows for the most convenient observing position and prevents fatigue, even after long hours of work. Moreover, the head rotates 360 degrees around its axis, which is really convenient for group work.
Illumination can be powered by AC power, as well as by batteries in case you want to do your research outside.
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.
Conducting microscope experiments
The microscope is great for experienced users as well as for complete beginners. Levenhuk K50 Experiment kit will help them make their first experiments and learn a whole bunch of new things about the microworld.

Tell me please if there's any significant difference in image quality between LEVENHUK Rainbow 50L and LEVENHUK Rainbow 50L PLUS? I've just read comments and it seems that 1280x magnification isn't that useful... you can't observe bacteria and images may get blurry. What objects will I be able to see with the PLUS model that won't be seen with 50l microscope? Levenhuk Customer Service:
The difference in quality won't be very significant. The advanced 50L PLUS model will give you a more detailed view.
Should I buy something in addition to this microscope? Or everything needed is included? Levenhuk Customer Service:
Levenhuk Rainbow 50L PLUS Moonstone Microscope comes with everything needed for your first observations and experiments. We also recommend that you pay attention to our prepared slides sets - https://www.levenhuk.com/catalogue/accessories/experiment-kits/.
Hello! I recently got this microscope. When I install 4x and 10x objectives, everything is good. But not with a 40x one. I can't see anything but black dots. I tried to move the stage in all possible ways, but nothing happened. What am I doing wrong? Levenhuk Customer Service:
When you observe at high magnifications with Levenhuk Rainbow 50L PLUS or any other microscope, the field of view becomes much narrower. Therefore it becomes harder to locate a sample. Always start from the lowest magnification - you will be able to easily locate, center, and focus the view. Then incrementally switch to higher increases to see more detailed views.
and what should I do if I need lower magnifications? Like 10x or 20x? This microscope minimum magnification is 64x, right? Levenhuk Customer Service:
Yes, Levenhuk Rainbow 50L PLUS Microscope provides 64x minimum magnification. You won't be able to get 10x or 20x magnifications with this model.
What is a hatchery for artemia used for? Levenhuk Customer Service:
It is used for growing Artemia.
Will I be able to replace eyepieces and objectives in order to increase magnification? Levenhuk Customer Service:
No, you won't be able to replace eyepieces and objectives on the Levenhuk Rainbow 50L PLUS Moonstone Microscope.
As far as I know, bacteria can be observed at 1000x magnification... and this microscope features 1280x maximum power. So why you tell that this microscope isn't suited for this purpose? Levenhuk Customer Service:
At maximum magnification image quality may be slightly decreased, therefore we recommend using a laboratory microscope for observations of bacteria. For example, Levenhuk 320 Biological Microscope - https://www.levenhuk.com/catalogue/microscopes/levenhuk-320/.

Levenhuk Rainbow 50L PLUS model allows for viewing moving microorganisms, for example Paramecium caudatum.
Greetings! Will I be able to see dust mites, microorganisms, bacteria, and ciliates? What are the advantages of the 320 model over 50L PLUS? Levenhuk Customer Service:
Levenhuk Rainbow 50L PLUS Microscope allows you to observe dust mites, microorganisms, and ciliates. To see bacteria you'll need a laboratory model, for example Levenhuk 320 Biological Microscope (https://www.levenhuk.com/catalogue/microscopes/levenhuk-320/).
