Levenhuk D900T Digital Microscope
Levenhuk D900T is a trinocular microscope with a 5.1 megapixel digital camera. It can be used for laboratory research of any level of complexity, as well as their photo and video recording. A digital camera allows you not only to record an image from the microscope lens, but also to transfer it to an external screen. Frame resolution – up to 2592x1944 pixels. The microscope will appeal to professionals - demanding specialists in various branches of science. The optical design includes wide-field 10x eyepieces and achromatic lenses of various magnifications. The 40x and 100x lenses have front lens protection - a spring frame. When making observations, you can use the “dry” method (all lenses) or oil immersion (only 100-mm objective). The trinocular head can be rotated 360°, the visual block is tilted 30°, and a separate vertical tube is used to mount a digital camera (included). Samples for research are placed on a sample table with a drug carrier. The lighting system is located at the bottom and is a 3-watt LED with a collector, the brightness of which can be adjusted. The light intensity can also be adjusted using an Abbe condenser with iris diaphragm and filter holder. An AC power connection is required to power the backlight. A digital camera is equipped with the necessary cables and software that allows you to crop a picture, change its size, adjust contrast and brightness, and otherwise process the resulting frames.
