The Levenhuk MED 40B binocular microscope has a professional plan achromatic optical system with Köhler illumination adjustment and 40x to 1000x magnification. The microscope will be useful for both a biochemist and a university professor. This optical instrument is suitable for various highly complex microscopic studies and helps you observe an object with a good degree of detail.

Plan achromatic infinity-corrected optics

The microscopes in the Levenhuk MED 40 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 40 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 binocular head that enables you to make observations with both eyes at the same time. The visual module is comfortably inclined by 30° – your neck muscles will not get tired even after long hours of observations. The head may be rotated around its axis by 360°. The microscope is quite useful for group observations when several researchers have to study the same specimen.

Optical capabilities

The kit includes such optical accessories as wide-field eyepieces and five infinity-corrected plan achromatic objective lenses. Eyepieces have 10x magnification, ensure clear vision, and enable diopter adjustment. The objective lenses minimize optical distortion, improve the contrast and color, and even the field of view. They are placed in the five-seat revolving nosepiece. High-magnification objectives have spring rims; a 100x objective lens allows using oil immersion in observations. All optic surfaces of accessories are protected with anti-fungal coating. The sharpness is adjusted with coarse and fine adjustment knobs.

Convenient work with microscope slides

The stage with a mechanical scale can move in two directions. The light source is located under the stage. It is a 5 W LED. The light intensity is adjusted by an Abbe condenser with an iris diaphragm.

Illumination is powered by an AC power supply. The light brightness is adjustable.

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.

Some things you can see under a microscope:

Levenhuk MED 40B 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.
