Levenhuk D450L LCD 7" Digital Microscope
Levenhuk D450L digital microscope is a professional-level optical device that can be used to solve many laboratory, medical and academic problems: conduct cytological, morphological and histological studies, study bacteria, microorganisms, cell cultures, examine various biological samples in classes at schools and universities. The microscope is perfect for long-term or group work, since the classic visual unit in its design is replaced by a 7" diagonal color LCD screen and a digital camera with a resolution of 2 megapixels. This design of the device protects the user's vision from overstrain, and the back and shoulders from pain due to an uncomfortable posture when working. The revolving device of the microscope is designed for 4 lenses, they are already installed: 4x, 10x, 40x and 100x. In combination with the basic capabilities of the device, they provide magnification in an impressive range from 40 to 1000 times. The lens optics are achromatic, providing a consistently clear, true and distortion-free image, regardless of viewing conditions and the current degree of magnification. The 40x and 100x lenses are spring-loaded, which means their lenses are protected from accidental damage. The 100x objective can also be used for oil immersion work (a bottle of special oil is included in the package). Levenhuk D450L microscope operates using the bright field method. A 1 W LED is used as backlight, on top of which there is a collector that enhances the glow. Above the backlight element is an Abbe condenser with an iris diaphragm and a special mount for a filter (filters are purchased separately).
