Levenhuk Rainbow 50L PLUS Moonstone Microscope would make a wonderful gift for an inquisitive teenager, biology student, or a laboratory technician. The maximum magnification power of this instrument is 1280x – just enough to see all the tiniest details of observed microscope samples. The model features a reliable, robust body - Rainbow 50L PLUS Moonstone Microscope can be used as an instrument at home, as well as for laboratory work in schools and universities.
High magnification power
The kit includes three objective lenses. The most powerful objective (40xs) is equipped with a protective spring-loaded mechanism. This mechanism ensures optics safety. Even if you lower the objective lens too much and touch the sample with it, the objective lens will retract, preventing any damage. The kit also includes 2x Barlow lens which increases the magnification two-fold. The microscope in its standard configuration produces 64x, 128x, 160x, 320x, 640x and 1280x magnification!
The optics are made of quality highly transparent glass. The lenses are coated with multiple layers of special anti-reflective coating. The images will always be bright, clear, and contrast - and that is especially important when working at high magnifications.
Combined illumination – explore a huge variety of microscope samples
This model is equipped with two LED illumination systems. The lower lighting is needed for viewing transparent samples. For example, you will be able to examine the structure of a bee’s wing or detect microorganisms in aquarium water. The upper lighting allows for observing non-transparent (opaque) objects such as paper or metal. This model can also be used for working with semi-transparent objects by using both upper and lower lighting at once. The illumination systems feature adjustable brightness.
Ergonomics and reliability
The microscope has a very reliable, robust body made of metal. The 45-degrees inclined and 360-degrees rotatable head ensures the most comfortable use of the instrument. That is especially convenient when working in a group – to get a better view, just rotate the head instead of moving the whole microscope.
This microscope can be also used outside the house – the illumination system can be powered through an outlet or with standard AA 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.
Levenhuk Rainbow 50L PLUS Moonstone Microscope comes with a special experiment kit. The Levenhuk K50 Experiment Kit is designed for children and adult beginners to perform their first independent experiments.

The user guide has all necessary information about the microscope and its design, tips on preparing microscope slides, and detailed experiment descriptions.

How to turn the condenser? Levenhuk Customer Service:
The condenser is a wheel located under the stage; just move it right-left to change the angle of illumination.
Where is the condenser and how to adjust it? What's with the wheel in the bottom of the microscope? Levenhuk Customer Service:
The condenser is a small lens system and is located under the microscope stage. The condenser allows you to collect and send more light, in order to change the angle of light you need to turn the condenser. At the base of the Levenhuk Rainbow 50L PLUS microscope, there are two wheels located on the right and on the left that serve to turn off the top or bottom illumination.

And why different colors of the microscope have different descriptions? Levenhuk Customer Service:
Levenhuk Rainbow 50L PLUS Microscopes differ only in colors.
What is a Barlow lens used for? how does it work? I know that if, for example, I use a 40x lens, then I get 400x magnification… Levenhuk Customer Service:
Barlow lens gives you an extra magnification. 400x magnification is achieved by using a 40x lens with a 10x eyepiece. Levenhuk Rainbow 50L PLUS Moonstone Microscope comes with a 16x eyepiece. Therefore, 16x eyepiece * 40x lens = 640x. 2x Barlow lens will provide 1280x magnification power.

Good afternoon! Does the microscope kit include a slide with a recess? I can not find it, but it is necessary. Thank you. Levenhuk Customer Service:
No, Levenhuk Rainbow 50L PLUS Moonstone Microscope comes with standard slides.
Why I didn't find camera, software for windows, and usb cable in the kit? And there were 2 batteries instead of 3… Levenhuk Customer Service:
Levenhuk Rainbow 50L PLUS microscope is not equipped with a camera, digital camera comes with the Levenhuk Rainbow D50L PLUS model (https://www.levenhuk.com/catalogue/microscopes/levenhuk-d50l/). The information on the website is correct: the microscope comes with 2 AA batteries.
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/.
