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.

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.
