The Rainbow 2L PLUS brightfield and stylus microscopes are the natural evolution of the Levenhuk Rainbow 2L series. The new microscopes combine all the advantages of the previous range with new, useful features. These microscopes are equipped with two illumination systems – so you can observe transparent, semi-transparent and opaque specimens.
Each model comes with a Levenhuk K50 experiment kit – this kit will help young researchers with their first experiments and independent research. The main difference with the new microscopes is their improved optical components. They offer higher magnification (up to 640x) and can be used for serious research by biology students. All microscopes are fitted with spring-loaded objective lenses – their design prevents any damage, even if the objective touches the slide during the focusing process.
Levenhuk Rainbow 2L PLUS microscopes have a reliable metal body – they are known for their long service life, even when used intensively in universities or laboratories. And, of course, we must mention their modern design and five vibrant colours – one of these beautiful microscopes will look great in your child’s room or on your coffee table.
Excellent
optical components
Levenhuk Rainbow 2L PLUS biological microscopes are made exclusively from the highest-quality materials. The lenses are made from a special, highly transparent optical glass. For better light transmission, the optical surfaces are coated with multiple layers of anti-reflective coating, which enhances the sharpness and contrast of the images produced.
The kit includes three objective lenses providing magnifications of 64x, 160x and 640x. The most powerful objective lens (40x) features a special spring mechanism to protect the optical elements.
Combined
illumination
One of the model’s main advantages is that the microscope is equipped with two LED illumination systems. The lower illumination is used to view transparent specimens, such as liquids or small sections of plants and animal tissue. The top illumination allows you to observe opaque objects – paper, minerals, fabric and metal. If you switch on both light sources, you can observe semi-transparent objects. You can adjust the brightness for better viewing.
Comfortable and durable
body
The robust body is made of metal – it can easily withstand frequent use and will serve you for many years. For added comfort, the monocular head is tilted at 45 degrees. Furthermore, it can be rotated through 360 degrees – which is very handy for group work; simply rotate the head without moving the microscope. The instrument can be used indoors and outdoors – the microscope operates via mains power or batteries.
Warning: Please refer to the specifications table for the correct mains voltage and never attempt to plug a 110 V device into a 220 V socket, or vice versa, without using a converter. Remember that the mains voltage in the United States and Canada is 110 V, and 220–240 V in most European countries.
Experiment
Kit
The pack includes the Levenhuk K50 Experiment Kit. It contains everything you need for your first experiments: ready-to-use microscope slides, special tools for preparing them, and a very useful guide with information about the microscope, usage tips and descriptions of experiments.
