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.
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.
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.

using a 40x lens sharpness appears when the stage is close to the lens (well, thanks it’s springy). is it ok? But in this case the lens obstructs all the upper light. I could only see the prepared samples. I covered my own samples with a slide (havent bought coverslips yet), and couldnt adjust sharpness, apparently this glass is too thick. Levenhuk Customer Service:
There is a spring 40xs lens in Levenhuk Rainbow 2L PLUS Microscope, and it should be lowered very closely to a cover glass with a sample for observation with only the lower illumination.
Hello! Do you have any suitable storage/transportation case for this microscope? Levenhuk Customer Service:
We do not have suitable cases for Levenhuk Rainbow 2L PLUS Moonstone in the product range. We recommend that you consider Levenhuk Rainbow 50L Microscope (https://www.levenhuk.com/catalogue/microscopes/levenhuk-50l-moonstone/).

How to properly use the disk with diaphragms integrated in the stage of the device? What position is considered standard (from which position of the disk should I start my observations) and what visible changes should I notice? Levenhuk Customer Service:
The diaphragm is a disk located beneath a high-powered microscope's stage, usually having five holes of different diameters. When turning the disk, the amount of light passing through the hole in the stage is changed - it helps to correctly illuminate different samples, increase their contrast and resolution. The largest aperture is standard.

Such microscope slides are required for experiments using the Hanging Drop method
Good time of day! We are looking for a family microscope, we have 7 yo kid. We take microscope as a mean of self-education and learning. Does it make sense to pay more for the 2L PLUS model? I mean as far as I know you can see a lot of interesting stuff under 400x, why pay extra? Maybe 2L PLUS with its 640x magnification is capable of something more? I heard somewhere that with high magnification images loose their 'volume'. Please help us decide on the right model. Thank you Levenhuk Customer Service:
Levenhuk Rainbow 2L PLUS does not loose in image quality while having higher magnification. Another advantage the PLUS model is a body made of metal.
