Levenhuk D320L BASE 3M Digital Monocular Microscope Monocular laboratory microscope with a digital camera and halogen illumination. Magnification: 40–1000x Levenhuk D320L BASE is a digital microscope with a 3M camera. It is great for performing observations in medical and clinical and diagnostic laboratories, holding seminars and lectures in academies and universities as well as in colleges, creating digital observational records. This microscope is very interesting to specialists of different scientific fields. It will become an excellent choice for professional microscopy observations. Levenhuk D320L BASE is a monocular microscope with a 360° rotatable head. A wide-angle 10x eyepiece and four achromatic objectives of different magnifications are used for observations. The magnification range varies from 40x to 1000x. You can apply oil immersion at maximum magnification (when using a 100x objective). A bottle of immersion oil comes included in the kit. The illumination system is located in the lower part of the microscope. It consists of a powerful halogen lamp with adjustable brightness and an Abbe condenser with an iris diaphragm. Illumination is powered by an AC supply. You can use light filters for adjusting image contrast. Specimens are fixed on a stage, which is equipped with a mechanical scale. Sharpness adjustment is performed by rotating coarse and fine focusing adjustment knobs. The kit includes a 3M digital camera. It allows for transmitting an image from a microscope to an external screen, e.g. a computer screen. You can make videos, take snapshots and process them with a special software program (an installation CD is included). The camera is powered by a computer with the help of a USB cable.
