Levenhuk MED 20T Optical Microscope
Levenhuk MED 20T trinocular microscope is a professional optical device for working with microspecimens at magnifications from 40 to 1000 times. It allows you to adjust lighting using the Köhler method and use oil immersion during observations. The microscope will be a godsend for an employee of a clinical diagnostic laboratory, department of biochemistry or microbiology, medical or health center, or scientific institute. The trinocular attachment is a binocular visual unit tilted at a 30-degree angle and a separate vertical tube into which a digital camera is installed (camera not included). The nozzle can be rotated around its axis - this function is useful for group studies, when several people must study one sample. There is a light flux divider. Optical accessories include wide-field eyepieces and semi-planachromatic lenses. The eyepieces provide 10x magnification and provide a good overview. For the convenience of users with imperfect vision, diopters can be adjusted on the eyepieces. The lenses provide different magnifications and noticeably flatten the field of view. The 40x and 100x lenses have spring-loaded frames. In addition, the 100x objective can be used for immersion observations. The optics are protected with an anti-fungal coating. There are coarse and fine sharpness settings. The object table is equipped with a preparation guide. Under the table there is an Abbe condenser and halogen lighting. The condenser has an iris diaphragm and a filter holder. The brightness of the backlight is adjustable. The backlight uses AC power to operate.
