Levenhuk 450M optical microscope, monocular
Levenhuk 450M Biological Monocular Microscope is a powerful optical instrument designed for in-depth study of the microworld, biological samples and organic preparations, which will be useful to professionals, students and interested amateurs. The device is used for general clinical medical diagnostics, laboratory research, research activities and educational purposes. Levenhuk 450M microscope has a monocular head mounted at an angle of 30° and rotating 360°. This provides a comfortable overview of the sample and ease of work in both individual and group formats. The wide-field eyepiece used in the design has a magnification of 10x and a field of view of 18 mm. The device has a diopter correction function within ±5 D, making it easy for people with visual impairments and wearing glasses to use. The microscope is equipped with optics that provide magnification from 40 to 1000 times and form a clear, bright and truthful image. The revolving device contains 4 achromatic lenses with magnifications of 4x, 10x, 40x and 100x; the latter can be used for observations using the immersion method (a bottle of oil is included in the delivery package). For convenient sample positioning, the design of the Levenhuk 450M microscope includes a 110x120 mm stage. Under the table there is an Abbe condenser with an iris diaphragm that regulates the flow of light, and special holders for installing light filters. The microscope is focused using the fine and coarse adjustment knobs of the coaxial system. Levenhuk 450M uses a 1 W LED with a collector as a light source, providing bright and uniform illumination of the drug. The microscope is powered both from a 100-240 V network via an AC adapter, and from 3 AA batteries - this makes the device mobile.
