Levenhuk 720B Optical Microscope
The Levenhuk 720B biological microscope with a binocular attachment will take its rightful place in any scientific or medical laboratory. It can be used to equip school classrooms, conduct lectures at universities, and conduct clinical trials within research enterprises. Levenhuk 720B microscope allows you to conduct studies in transmitted light using the bright field method. The object of research is transparent samples and micropreparations. The microscope has a wide magnification range from 40x to 2000x, within which you can select several fixed magnifications. The optimal magnification is selected by rotating the turret with lenses or replacing standard eyepieces. The microscope comes with two basic sets of wide-angle eyepieces: WF10x and WFH20x. Levenhuk 720B microscope is equipped with a binocular attachment, which significantly increases comfort during long-term observations. The load is distributed over both eyes, which reduces visual strain. The nozzle can rotate around its axis. Its tilt angle is 45°. The microscope lenses are achromatic, reducing distortions and aberrations. At maximum magnification, you can use the immersion research method, which allows you to enhance the brightness of the samples being studied. The magnification range and depth of field also increase. A bottle of immersion oil is included. Microspecimens should be placed on the stage and fixed with special clamps. The lighting system is located at the bottom, so only transparent samples can be observed. The light source is a bright 3 W LED. Its brightness is adjustable, allowing you to fine-tune the light level. The light beam also passes through an Abbe condenser with an iris diaphragm, which makes it possible to precisely focus the light on an object, adjusting the diameter of the aperture hole and, thereby, the light beam. The backlight works from the network. To accurately focus on individual parts of a microspecimen, you can move the stage vertically or horizontally and use a fine or coarse focusing system. Levenhuk 720B microscope has a reliable metal body, which ensures durability of the entire optical system. To protect against dust, the package includes a special storage case.
