The Levenhuk D740T digital microscope is designed for both eyepiece observation and data transmission to a PC monitor. The microscope is equipped with a modern 5 Mpx camera to be installed on the eyepiece tube to transmit images to a PC screen in real time. Since the microscope is equipped with a trinocular head, it is always possible to cast one eye (or in our case, both) on the sample through the eyepieces.
The microscope has a wide range of magnifications available: from 40x to 2000x. To choose the appropriate magnification factor, simply rotate the nosepiece and change the eyepieces. The kit includes four achromatic objectives (including an immersion lens) and two sets of eyepieces.
The Levenhuk D740T microscope is designed for observing transparent samples. The lighting system is positioned under the table and is equipped with a practical brightness adjustment. The light source is a 3 W LED. Its brightness is continuously adjustable over a wide range. The lighting is powered by the mains (power cable included). The light coming from the source is directed towards an Abbe condenser equipped with an iris diaphragm. By adjusting the diameter of the aperture, you can focus the light beam on the desired area. Coarse and fine adjustment is performed via a focus knob.
The microscope stage is equipped with metal clips to securely fix the sample and can be moved vertically and horizontally. The body is made of metal.
In addition, the microscope kit includes the Levenhuk D740T digital camera and its accessories. When installed in place of an eyepiece, the camera will show everything that happens under the objective lens on the connected PC screen. This feature can be used for presentations or to save your search results in photo or video format for future use. Levenhuk software (included in the kit) allows you to edit the images you take: changing size, adjusting brightness and contrast, cropping images, and so on.
The kit includes everything you need to start working. Your digital camera comes with an installation CD, which contains the necessary software and drivers. The Levenhuk D740T and its camera are compatible with Windows, Linux and Mac OS.
