Levenhuk 740T – microscope with trinocular head, allows you to carry out biological studies with classic observations combined with the use of modern technologies. The trinocular head allows the installation of any digital camera suitable for the eyepiece tube with a diameter of 23.2 mm.
The microscope features bottom illumination, which means that only transparent samples can be observed. The light intensity is adjustable within a wide range. An Abbe condenser repeatedly amplifies the light beam and directs it exactly to the area of interest. This microscope allows observations in bright field mode. The use of oil immersion is also possible.
The nosepiece is designed to accommodate four objective lenses. By combining them with interchangeable eyepieces with various magnification factors, a wide range of predefined magnifications between 40x and 2000x can be achieved. All eyepieces in the kit are paired.
The trinocular head is inclined at 45° and rotates 360° around its axis. This is particularly convenient for group work, or where it is useful to allow multiple people access to observe the sample: simply rotate the microscope head instead of moving the entire instrument.
The samples are fixed to the table using two practical metal clips. The stage itself moves horizontally and vertically, allowing you to accurately determine the working area and focus on a small part of the sample. The focus mechanism allows you to adjust sharpness coarsely and finely. Most amateur microscopes do not have this useful feature.
The microscope is equipped with a special dust cover for more convenient storage of the instrument.

Caution: Refer to the specification table for the correct mains voltage and never attempt to connect a device from 110 V into the 220 V socket and vice versa, without using a converter. Remember that the mains voltage in the United States and Canada is 110 V and 220–240 V in most European countries.
Some of the things that can be observed under the microscope:




The Levenhuk 740T trinocular microscope is compatible with Levenhuk digital cameras (purchased separately). Levenhuk cameras are installed in the eyepiece tube, in place of an eyepiece.
