Levenhuk 3S NG Monocular Microscope

With the Levenhuk 3S NG, you can begin your adventures in the world of science as soon as you take the microscope out of the box, thanks to the included experiment kit. This model allows for brightfield observations of transparent specimens. With its 200x magnification, this microscope is a fantastic gateway to the wonders and mysteries of the microcosm for children, students and amateur enthusiasts.

The 40 mm (1.6 inch) plano-concave mirror in the Levenhuk 3S NG models provides sufficient light for your observations, meaning you can use the microscope without having to connect it to a power source. This is the simplest and safest method of illumination, meaning the microscope can be easily used by children. The diaphragm allows you to control the amount of light required for observing your sample.

This monocular microscope features a single 16x achromatic objective lens, which provides a clear view free from chromatic or spherical aberrations. In this model, the head is positioned directly on the stage, but for comfortable observations, you can tilt both the head and the stage to the desired angle using the microscope arm.

The 100 × 90 mm (3.9 × 3.5-inch) stage is ideal for observing one or two specimens. To prepare the specimen, first place a specimen on a blank slide, then gently lower a cover slip over the specimen. The final slide is then placed on the stage and secured with clamps. Use the coarse focus knob to focus your view by moving the microscope body tube up and down (in 20 mm (0.8 inch) increments).

The metal construction makes this microscope sturdy and stable.

The user guide “Fascinating Microscope: Exploring the Microcosm”, included in the kit, will guide you through a wide range of biological experiments that you can carry out at home. To do this, you’ll use the samples already supplied with the Levenhuk 3S NG microscope; and in just a few minutes, you’ll be looking at the unknown. You’ll learn how to prepare samples, carry out experiments, analyse the results and, of course, learn a great deal about the world around you.
