Levenhuk D740T digital microscope is designed for both visual observations through the microscope eyepiece and for data transmission to a PC monitor. The microscope comes with a modern 5 Mpx camera that you install in the eyepiece tube to transmit images to a PC monitor in real time. As the microscope has a trinocular head, you can at the same time keep an eye (in our case both eyes) on what’s happening through the eyepieces.

The microscope has a wide range of available magnifications: from 40x to 2000x. Choose the right magnification power by turning the revolving nosepiece with objectives and changing eyepieces. The kit includes four achromatic objectives (including an immersion lens) and two eyepiece sets.

Levenhuk D740T Microscope is designed for viewing transparent microscope samples. The illumination system is located below the stage and has а convenient brightness control. The light source is bright LED (3 watts). Its brightness is continuously adjustable over a wide range. Illumination is powered by household current (power cord is included). The light from the source is redirected to the Abbe condenser equipped with iris diaphragm. By adjusting the aperture opening, you can precisely focus the light beam at the desired area. Coarse and fine sharpness adjustment is done with a focusing knob.

The microscope stage is equipped with metal clips to securely fix the specimen and can be moved in horizontal and vertical directions. The body is made of metal.

The microscope kit also includes the Levenhuk D740T digital camera and accessories. When installed in place of an eyepiece, it will show you everything that’s happening under the objective lens on your PC monitor. This feature can be used for presentations or for saving the results of your studies in photo and video formats for future use. Levenhuk software (included in the kit) allows you to edit received images: change their sizes, adjust brightness and contrast, crop and so on.

The kit includes everything you will need to start working. The digital camera comes with an installation CD that contains the necessary software and drivers. Levenhuk D740T and its camera are compatible with Windows, Linux and Mac OS.

Questions and Answers
Sem Castillo (2018.02.10)
hello! Levenhuk d70l that I bought here not a long time ago is very similar to d740t model. Is there any possibility to acquire the upper part of the latter with a camera instead of a full new microscope? I’m just looking for a way to upgrade the model so that I could display images in real time on a monitor. Thanks in advance for your help.
