Levenhuk D400T Digital Microscope
Levenhuk D400T Digital Microscope is a light model for biological research, which is complemented by a 3.1 megapixel digital camera. This means that the device can be used not only for visual observations, but also for photographing samples, video recording of research, and broadcasting images from the lens to an external screen. Frame resolution – up to 2048x1536 pixels. The microscope is an excellent choice for work in a laboratory, veterinary office or educational institution. The microscope is equipped with a trinocular attachment. The visual part has a slight slope, so long studies cause less fatigue. The eyepiece tube for a digital camera (included) is positioned vertically. The optical system includes two wide-field eyepieces with 10x magnification, as well as four achromatic objectives with magnifications of 4x, 10x, 40x and 100x. The 40x and 100x lenses have front lens protection in the form of a spring frame. In addition, the oil immersion method can be used with a 100x objective. A slide driver is used to install microslides on the object table. The lighting is located at the bottom and is a 1-watt LED with a collector. The brightness of the backlight can be adjusted. You can also adjust the intensity of the light flux using an Abbe condenser with an iris diaphragm. It is possible to use light filters. Along with the digital camera, software for it is also included in the package. It allows you to process the received images: crop the picture, change its size, adjust the contrast and brightness, and otherwise process the received frames. Levenhuk D400T microscope is compatible with Levenhuk digital cameras (cameras sold separately). Levenhuk cameras are installed in the eyepiece tube instead of the eyepiece.
