Levenhuk 740T Microscope – trinocular microscope, which enables you to carry out classic biological studies and employ modern technology in your observations. Trinocular head allows you to install any digital camera adapted to the 23.2mm eyepiece tube.

The microscope is equipped with lower illumination – that means you can observe only transparent microscope samples. The intensity of light is adjustable over a wide range. An Abbe condenser repeatedly amplifies the light beam and directs it exactly on the area of research. The microscope allows for observations in the bright field mode. It also allows using the oil immersion method.

The revolving nosepiece is designed to accommodate four objective lenses. Combining them with interchangeable eyepieces of different magnification, you can obtain a wide range of fixed magnification in the 40x-2000x range. All eyepieces that come in the kit are paired.

Trinocular head is inclined at 45° and rotates 360° around its axis. This is especially convenient for group work, when you need to let a wide audience access the observed samples – just turn the microscope head, instead of moving the whole instrument.

Samples are fixed on the stage using two convenient metal clips. The stage itself moves vertically and horizontally, allowing you to accurately determine the area of research and focus on a small part of the sample. The focusing mechanism allows for fine and coarse sharpness adjustment. Most amateur microscope models lack this useful feature.

The microscope comes with a special dust cover for convenient storage of the instrument.
