Levenhuk D90L LCD Digital Microscope
Levenhuk D90L LCD Digital Microscope is a biological microscope with a 2 MP digital camera. It does not have a classic eyepiece attachment - it is replaced with an LCD screen, which is much more convenient to use for long-term observations. The image is transmitted to the screen from the lens in real time; in addition, there is a photo and video recording function. The microscope is suitable both for conducting microbiological research and for creating digital archives of observations. The screen attachment can be rotated 360°. It contains digital camera control buttons, connectors for connecting external devices and a memory card slot. The lenses are already installed in the revolving device - these are achromatic lenses with magnifications of 4x, 10x, 40x and 100x. The 40x and 100x lenses have spring-loaded frames that protect the front lens from accidental damage. The 100x objective is used for oil immersion. Under the revolving device there is a subject table with a preparation guide. Below is an Abbe condenser with iris diaphragm and filter holder. Even lower is the backlight unit, namely an LED with a collector. The backlight runs on AC power and its brightness can be adjusted. All optical elements of the microscope are made of glass, the body is made of metal.
