Levenhuk Rainbow 2L PLUS Amethyst Microscope will be a perfect choice for a pupil who loves biology, as well as for a medical student for serious research. This model has many advantages: high-quality multi-coated optics, a wide range of magnification from 64x to 640x, ability to observe both transparent and opaque objects, and reliable body. Beginners will definitely appreciate the Levenhuk K50 Experiment Kit that comes with the microscope. Moreover, Levenhuk Rainbow 2L PLUS Amethyst Microscope stands out from other similar biological microscopes thanks to its beautiful and colorful design.

High-quality optics
A microscope’s image quality directly depends on the quality of optics. That’s why Levenhuk Rainbow 2L PLUS microscopes are made with only the highest quality materials. All lenses are made of a special optical glass - it is highly transparent and does not distort the image. The lenses are additionally coated with anti-reflective coating, which increases the percentage of transmitted light and, therefore, image brightness and contrast.
The revolving nosepiece has three objectives producing 64x, 160x, and 640x magnification. In order to change magnification power, you need to switch objectives by rotating the nosepiece. The most powerful 40xs lens is equipped with a spring-loaded mechanism – fragile optical elements will be safe even when a non-experienced user lowers the objective too far and touches the sample with it.

Observing transparent and opaque samples
The microscope is equipped with two illuminators, upper and lower, allowing you to observe both opaque and transparent samples. In order to observe microorganisms in a drop of water or a plant cell structure, use the lower illumination. The upper lighting is used for viewing opaque objects – you can evaluate paper quality or detect invisible scratches and dents on coins. Semi-transparent objects should be observed with both upper and lower illumination. The brightness can be adjusted for the best possible view of a particular sample.

Well-thought-out design
The reliable metal body of the microscope allows for frequent use. The 45-degree inclined monocular head allows for most comfortable viewing position. It also rotates 360 degrees around its axis – this feature is really useful for group work.
To power illumination, the microscope should be connected to a power source. If there is no power outlet nearby, you can use batteries - this is especially useful when conducting 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.

Help your kids get higher grades in biology and chemistry classes. Spark their interest in science with Levenhuk Rainbow 50L PLUS Orange Microscope! The microscope comes with an excessive kit of additional accessories. It includes ready-to-use microscope slides and tools for making your own samples and for breeding crustaceans–along with many other useful things. It can be successfully used by a school child, student, or even a laboratory technician. Levenhuk Rainbow 50L PLUS Orange Microscope has a beautiful colorful design and would be a nice gift for anyone interested in the microcosm!

High-quality optics
This microscope model comes with three objectives producing 64x, 160x, and 640x magnification. 40xs objective lens is equipped with a special spring-loaded mechanism, which protects the optics from mechanical damage. If you lower the objective too much and it touches the microscope slide, 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 configuration of the model allows you to obtain up to 1280x magnification power!

The optics are made of high-quality multi-coated optical glass - you will always get clear, sharp, and highly detailed images of observed objects.

Illumination for observing transparent and opaque objects
The microscope is equipped with two bright LED illuminators. The lower illumination allows for observing transparent samples in transmitted light – for example, you can observe ciliates, or study the structure of indoor plants. Upper illumination is used for viewing opaque samples such as paper or cloth. If you turn both illumination systems on, you will also be able to observe semi-transparent objects. You can adjust the brightness level to achieve the best viewing results for a particular microscope sample.

Durable and convenient body
The durable metal body ensures the microscope’s long service life. It is suitable for individual use at home, as well as for intensive everyday use in schools, colleges, and laboratories. The monocular head is inclined at an angle of 45 degrees for the most comfortable viewing position. Moreover, the head rotates 360 degrees around its axis and can be successfully used for working in a group of people.

The microscope can be powered through an AC outlet, as well as run on 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.
