Levenhuk D740T Digital Microscope
Levenhuk D740T digital microscope – with a trinocular attachment, is equipped with a 5 megapixel camera, which, when connected to a computer, displays images of the samples under study on its screen. At the same time, the user can continue to examine the preparations through the eyepieces and perform the necessary manipulations with them. This method of working is especially in demand during presentations, lectures or group studies, when the result of research needs to be demonstrated to a wide range of people in real time. The microscope eyepiece is tilted at an angle of 45°. This angle of inclination is most convenient for long-term observations: the load on vision and the cervical spine is reduced. The nozzle can be rotated 360°. The revolving device is designed for four lenses; in the delivery set you will find achromatic and oil lenses. Interchangeable eyepieces of different magnifications are also included in the kit. The microscope provides a large number of fixed magnifications ranging from 40 to 2000 times. The backlight is located in the lower part, under the object stage, and has smooth brightness adjustment. An Abbe condenser with an iris diaphragm is used to precisely focus light on the area of interest. The included filters help highlight details and increase image contrast. The microscope allows you to examine transparent samples using the bright field method. Let us note the presence of an object stage with coordinate movement. It can be moved vertically and horizontally. Sharpness adjustment occurs over a wide range thanks to the coaxial fine and coarse adjustment mechanism. Together with the Levenhuk D740T microscope you get a modern 5-megapixel Levenhuk D740T digital camera. It connects to a computer using the included USB cable and allows you to display images of the samples under study.
