Levenhuk 400M Monocular Microscope (75419)

The Levenhuk 400M Monocular Microscope is designed for laboratory research on biological samples. It produces sharp, high-contrast images and supports observations at magnifications ranging from 40x to 400x. The microscope is suitable for use in medical, educational, and research environments. It features built-in LED illumination that can operate either on batteries or via an AC power supply.

Optical system and viewing comfort

The optical system combines a wide-field eyepiece with achromatic objectives of different magnifications. This configuration is well suited for examining medium-sized and larger structures. The monocular head is inclined at 45 degrees for comfortable viewing and can rotate 360 degrees, making the microscope convenient for both individual use and group demonstrations.

Stage, focusing, and condenser

The stage is fitted with two specimen holders. Directly beneath it is an Abbe condenser equipped with an iris diaphragm. A dedicated holder allows the installation of light filters, with blue, green, and yellow filters included in the kit. Focusing is performed using a standard coaxial system that provides both coarse and fine focus adjustments.

Illumination and power options

Illumination is provided by an LED light with a collector, located at the base of the microscope. Brightness can be adjusted to suit different specimens and observation conditions. Thanks to battery-powered operation, the Levenhuk 400M is portable and can be used in locations without access to mains electricity.

Construction and durability

The microscope body is made of metal, ensuring durability, stability, and a long service life.
