Levenhuk Rainbow 50L PLUS 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 Microscope can be used as an instrument at home as well as for laboratory work in schools and universities.

Quality optics
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 illumination sources. To observe transparent samples such as thin plant cuts 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.

Ergonomic body
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.

Reliable and convenient case
Robust plastic case provides safe transportation of the microscope and all the accessories included in the package.
