The Levenhuk MED D25T is a trinocular head digital microscope with 5.1 MP camera, planachromatic optics and two condensers (bright field and dark field). It can be used in various scientific fields: medicine, biochemistry, microbiology and more. This microscope is the perfect choice for laboratory workers, university professors and researchers in medical centers or research institutes.
Rotating head with beam splitter
It is equipped with a trinocular head with beam splitter. The binoculars for stereo vision have a practical inclination angle of 30°, while the third eyepiece tube is vertical and houses the digital camera. This design allows you to perform classic observation in parallel with the use of the camera, to transmit images to an external screen and simultaneously capture photos and videos. The head is practical to use also thanks to the possibility of rotating it 360°.
Observations without optical aberrations
This microscope uses planachromatic objective lenses, which they create a very flat field of vision and reduce chromatic aberrations. The objective lenses with 40x and 100x magnification are equipped with a spring mechanism. Furthermore, the 100x objective lens can also be used with oil immersion. The wide-field eyepieces feature diopter adjustment and provide 10x magnification. The objective lenses and eyepieces have received an anti-mold treatment.
Digital capabilities
The sensor in the digital camera is capable of providing sharp, detailed images of observed samples. You can capture videos with high frame rate, which ensures very smooth videos. The software included in the kit allows you to set up the digital camera and process the captured photos and videos. The software allows you to change image size, brightness and contrast, exposure time and white balance, calibrate the camera and objective lenses, as well as measure specimens and structures (various units of measurement available). The included UBS cable is used to connect the camera to the computer. A trinocular microscope with digital camera makes long hours of work in the laboratory easier. The image observed through the objective lens is also transmitted to an external screen. There is therefore no need to continuously observe through the eyepiece, thus avoiding straining your vision and shoulder joints.
Work comfortably with slides
The table is equipped with a mechanical slider. Sharpness adjustment is achieved by rotating the two fine or coarse focus adjustment knobs. An Abbe condenser is positioned below the stage and is equipped with an iris diaphragm and filter holder. The kit includes a condenser suitable for studying samples in dark field. The lighting system consists of a 20W halogen lamp with adjustable brightness. Köhler illumination can be configured. The illumination is powered by AC mains electricity.
The Levenhuk MED 25 series includes microscopes ideal for cytology that allow bright and dark field observations with oil immersion.

Caution:
Refer to the specification table for the correct mains voltage and never attempt to plug a 110V device into a 220V outlet, or vice versa, without using a transformer. Please note that the mains voltage in the United States and Canada is 110 V and is 220–240 V in most European countries.
