Levenhuk 890T optical microscope, trinocular
Levenhuk 890T is a trinocular biological microscope for working in bright field at a magnification of 40 to 2000x. It is used for observations of various profiles: laboratory diagnostics, research, training events. The microscope will be in demand among specialists working in the fields of forensics, veterinary medicine and many others. The trinocular visual attachment is one of the advantages of this model. The presence of a separate imaging channel for a digital camera provides the potential to expand the capabilities of the microscope. By equipping it with a video eyepiece of your choice, you have the optimal system for visual observation and documentation of your work. The package already includes a C-mount adapter, which is used to attach a digital camera to the imaging channel - you do not have to purchase it separately. The eyepiece part of the nozzle is tilted at an angle of 30 degrees - this is an ergonomic arrangement that makes long-term work with the microscope more comfortable. The eyepieces in the attachment can be changed; the set includes paired eyepieces with magnifications of 10x and 20x. Adjustment of interpupillary distance is provided. The lenses are installed in a revolving device with four free slots. Planachromatic optics effectively remove distortions in the image, so samples are visible clearly, without blurring of small details and parasitic visual artifacts. The revolver rotates predictably and effortlessly. High power lenses - 40x and 100x - have front lens protection, which makes focusing easier when using them. In addition, the 100x lens is designed for oil immersion - this observation method can be used when working with it. Focusing is performed by two coarse and fine adjustment knobs, they are located coaxially on both sides of the tripod. The object table has a classic design - it moves along two axes, and is equipped with a preparation guide. The lower location of the backlight serves to work in transmitted light. The condenser is a classic Abbe, with a premium iris diaphragm. Since there is also a field diaphragm, the microscope allows you to adjust the lighting using the Köhler method. A halogen lamp is used as a light source. It provides “warm” lighting with a minimum of flickering, so it not only creates a well-lit working field, but also does not unnecessarily strain the eyesight. The backlight works from the network. If necessary, you can use a mirror to illuminate the sample - it is included in the package. You can increase the contrast of the picture using light filters, which are also included in the kit.
