The Discovery optical products series, manufactured by Levenhuk and endorsed by Discovery, is presented. The Discovery Femto Polar microscope is a classic monocular microscope that allows exploration of the world of microorganisms with magnification from 40x to 400x. It can reveal the cellular structure of plants and insects, life in a drop of water, protozoa, and much more. The microscope is an excellent assistant in the classroom for conducting simple biological experiments. An educational book about the world of microorganisms is included, making the experiments even more interesting and diverse.

The achromatic optics provide clear and detailed imaging of the samples. The device's rotating head has three objective lenses: 4x, 10x, and 40x with spring mechanism. The wide-angle mirror offers clear observation at 10x magnification. The monocular head is ergonomically inclined at 45°, making it more comfortable for prolonged observations. Additionally, the head rotates 360 degrees horizontally, which is excellent for group experiments. The microscope does not need to be moved to share the image with a partner, as the head can be rotated accordingly.

It is equipped with separate adjustment knobs for coarse and fine focus, allowing for smoother focus adjustments. The lighting system includes upper and lower LED illumination with brightness control. The lower light passes through a diaphragm disc, which also helps to control brightness. The device can operate with batteries (included) or with power supply (AC adapter included). The platform is equipped with clips for securely holding slides.

The book "The Invisible World" is a fascinating addition to the microscope. It reveals the world of microorganisms and explains scientific experiments. Written in easy language and featuring vibrant illustrations, it presents historical facts about microscopy and microorganisms, as well as experiments that can be conducted at home using the Discovery Femto Polar microscope.
