Levenhuk 450T optical microscope, trinocular
Levenhuk 450T biological microscope with a trinocular attachment and a total magnification of 40–1000 times is used in the fields of healthcare, medicine, pharmacology, biology, ecology, in laboratories, universities and research institutes. The capabilities of the microscope allow it to be used to solve many professional and academic problems: for detailed study of cells, biological samples, bacteria, microorganisms, tissue cultures, for cytological, morphological and histological studies. Observations are made using the bright field method in transmitted light; it is possible to use oil immersion. The visual attachment has a tilt angle of 30° and can be rotated to the most convenient position for work in the range from 0° to 360°. The design uses WF10x/18 mm wide-field eyepieces with a mounting diameter of 23.2 mm. For users with visual impairments and those wearing glasses, a diopter adjustment function of ±5 D is provided, which enhances the ease of use of the device and reduces eye strain during long-term observations. The revolving device of the microscope has 4 achromatic objectives for 4, 10, 40 and 100 times; Such optics will provide a consistently clear, sharp and truthful image without aberrations, distortions and vignetting. The 40x and 100x lenses are spring loaded, and the 100x lens can also be used for oil immersion. The Levenhuk 450T microscope is illuminated by an LED with a collector, above which there is an Abbe condenser with an iris diaphragm and a special holder for a light filter (light filters are purchased separately, depending on the user’s needs).
