The Levenhuk MED 45B binocular microscope is created for professional bright or dark field as well as for phase contrast microscopic studies. Oil immersion may be used for bright field, whereas in dark field observations only the “dry” method is used. The infinity-corrected optical system enables supplementing the microscope with additional accessories (purchased separately) to extend its capabilities. The microscope will be a perfect asset for an academic department, research institute, or medical laboratory.

Advantages of a phase-contrast method

It is noteworthy that phase-contrast microscopy allows for using this optical instrument. This method improves the contrast and sharpness of semi-transparent and transparent microscope slides up to a level that can be only reached by dying slides during a standard research method. That is why phase-contrast microscopy is indispensable during studying live specimens in their native state, as dying them inevitably leads to their death. This method can be applied for drinking water analysis, parasitic, cytological, hematological, and other research.

Plan achromatic infinity-corrected optics

The microscopes in the Levenhuk MED 45 series are equipped with an infinity-corrected optical system that is used in professional and high-class microscopes. This system includes Infinity PlanAchromat objectives and allows for obtaining clear, high contrast images with a high level of flatness.

One of the most important features of an infinity-corrected optical system is that it allows for installing any additional parts in the optical path between objective lenses and an ocular tube. The additional parts include polarizers and epi-fluorescence light. All in all, modular design and simple operation make Levenhuk MED 45 optimal microscopes for use in different kinds of microscopy and working in hematological, histological, microbiological, and other laboratories.

Binocular rotatable head

The microscope is equipped with a classic binocular head inclined at 30°. It enables you to make observations with both eyes at a time and prevents tensing your neck muscles during long hours of work. The head can rotate by 360°, which helps in group work – a specimen can be comfortably studied from any position. Eyepieces included in the kit have 10x magnification, ensure clear vision, and enable diopter adjustment.

Capabilities of the optical system

The revolving nosepiece allows for positioning up to five objectives, but it should be noted that only four objective lenses of various magnification are included in the kit. These phase contrast plan achromatic objective lenses even the field of view, improve color rendering, and reduce optical distortion. Two objectives with the maximum magnification are fitted with spring rims that protect them from incidental damage. A 100x objective lens is used for oil immersion. All the optic surfaces of accessories in the kit are protected with anti-fungal coating.

Convenient work with microscope slides

You can adjust sharpness by turning the coarse and fine focusing knobs. The double-layer mechanical stage is equipped with a mechanical scale. The stage can move in two directions. The phase contrast condenser is located below. A 5 W LED with brightness adjustment is used for the illumination of specimens. You can set up Köhler illumination.

Illumination is powered by an AC power supply.

Caution:

Please refer to the specifications table for the correct mains voltage and never attempt to plug a 110V device into 220V outlet and vice versa without using a converter. Remember that mains voltage in the U.S. and Canada is 110V and 220–240V in most European countries.

Levenhuk MED 45B Binocular Microscope is also compatible with other Levenhuk digital cameras (additional cameras are purchased separately). Levenhuk cameras are installed in the eyepiece tube instead of an eyepiece. This microscope is also compatible with any other digital microscope cameras.
