Levenhuk MED 25T Trinocular Microscope (73993)

Levenhuk MED 25T Trinocular Microscope is a professional optical instrument designed for laboratory research. It supports both bright field and dark field observation methods, allows Köhler illumination, and provides magnification up to 1000x. This makes it ideal for universities, medical institutions, research laboratories, and scientific centers.

Optics and Head
The trinocular head includes a visual part and an ocular tube where a digital camera can be installed (purchased separately). It is suitable for group research thanks to its 360° rotatable head and 30° inclination. A beam splitter is included. The microscope comes with wide-field 10x eyepieces that include diopter adjustment, making it easy to customize for individual users. The revolving nosepiece holds four plan achromatic objective lenses with different magnifications, designed to reduce chromatic aberrations and provide a nearly flat field of view. Two of these objectives have spring-loaded frames. The 100x objective supports oil immersion. All optical surfaces have an anti-fungal coating.

Stage and Focusing
The double-layer stage with a mechanical scale enables precise specimen positioning. Coarse and fine focusing knobs allow accurate focusing with smooth and precise movement. An Abbe condenser with an iris diaphragm and filter holder is located under the stage, used for bright field work. A dark field condenser is also included and supports oil immersion.

Illumination
The built-in lighting system is located at the base of the microscope. It uses a 20W halogen bulb with adjustable brightness and is powered by an AC supply.

Main Features

• Trinocular head with beam splitter

• Plan achromatic optics with magnification from 40x to 1000x

• Anti-fungal coating on all optical surfaces

• 20W halogen illumination powered by AC supply

• Köhler illumination support

• Suitable for bright field and dark field observations

Caution
Always check the specifications table for the correct mains voltage. Do not plug a 110V device into a 220V outlet, or vice versa, without a converter. In the U.S. and Canada, mains voltage is 110V, while in most European countries it is 220–240V.

Compatibility
The Levenhuk MED 25T Trinocular Microscope is compatible with Levenhuk digital cameras (sold separately), which can be installed in the eyepiece tube. It also works with other digital microscope cameras.
