Levenhuk MED D20T LCD Microbiology Digital Microscope is a professional optical instrument for bright field observations. Its main feature is a 5MP digital camera with an LCD screen that can transmit an image from a microscope objective in a real-time mode, and it allows for shooting videos and taking pictures of research. In addition, the microscope uses semi-plan achromatic optics and allows for setting up Köhler illumination. This microscope is useful in solving a wide range of problems in a field of microbiology, medicine, and research in various scientific fields.

High-class semi-plan achromatic optics

Trinocular 360° rotatable head has a binocular visual part, which is inclined at 30°. There is a beam splitter. A digital camera is installed in the vertical tube. Wide-field eyepieces provide good visibility and allow for diopter adjusting. The objective lenses feature various magnifications; 40x and 100x objectives have protective spring-loaded frames. You can conduct observations at maximum magnification using oil immersion (a bottle with immersion oil is included in the kit). The optics are protected by an anti-fungal coating.

Convenient work with microscope slides

There is a stage under the optics unit. The double-layer stage is equipped with a mechanical scale. The coarse and fine focusing knobs with small pitch allow for sharpness adjustment. The observations are held in the transmitted light: a 20W halogen light source is located under an Abbe condenser, which is equipped with a diaphragm and filter holder. The kit includes three light filters. The light brightness is adjustable; it is powered by an AC power supply.

Levenhuk MED D20T LCD is a modern microscope for microbiology research

A digital camera is also worth mentioning. In addition to an LCD screen, this camera is compatible with a lot of additional equipment. You can connect a mouse, keyboard, and headphones to the camera. An image from an objective lens can be transmitted to a built-in or external screen; flash drives and memory cards are supported. The camera does not require installing additional software. With the help of the utility software, you can edit recorded photos and videos, choose location for files storage, change camera settings, or perform simple processing of photos and videos. The software allows for adjusting size, image brightness and contrast, gamma, sharpness and saturation, exposure time and white balance, calibrating a camera and objective lenses, measuring specimens or structures (several measurement units are available). In addition, the program allows for carrying out a particle analysis. The camera makes working in a laboratory easier and more practical for an explorer: there is no need to observe slides through eyepieces as an image can be seen on a built-in LCD screen with sensor control.

The Levenhuk MED 20 series includes high-class microscopes for a microbiology laboratory.

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.

Some things you can see under a microscope:

Levenhuk MED D20T LCD Digital Trinocular Microscope is also compatible with other Levenhuk digital cameras (additional cameras are purchased separately). Levenhuk cameras are installed in the eyepiece tube instead of an eyepiece. This microscope is also compatible with any other digital microscope cameras.
