Levenhuk 740T Biological Microscope (SKU: 69657)

The Levenhuk 740T microscope is an exceptional three-eyed instrument suitable for a wide range of applications, including laboratory work, clinical tests, and medical research. It caters to the needs of professionals engaged in serious scientific investigations as well as individuals with a passion for transparent microscopic specimens. This microscope is highly recommended for both professional and home use, providing invaluable assistance in learning and fostering curiosity. Its versatile features make it ideal for veterinary research, didactics, and the observation of blood cells, thanks to its extensive magnification range and excellent lighting capabilities.

One of the standout features of the Levenhuk 740T microscope is its comfortable three-spotted head. The utilization of two eyes during observations significantly enhances the field of vision, ensuring extended periods of use without discomfort or fatigue. The head is inclined at 45° and can rotate around its axis, allowing users to effortlessly share their work progress with others without having to move the entire instrument.

The microscope is equipped with a third optical path that enables the attachment of a microscope camera or a regular camera (using dedicated adapters). This feature allows for photographic documentation and real-time viewing, opening up possibilities for visual observations and analysis.

Designed for observing transparent microscopic specimens, the Levenhuk 740T microscope supports various test methods, including bright field observation and the use of immersion oil. The set includes high-quality achromatic lenses and a bottle of immersion oil. Additionally, the microscope comes with two pairs of interchangeable eyepieces: a Huygens eyepiece and an eyepiece with a wide field of view. This comprehensive accessory kit provides users with the flexibility to choose the optimal magnification and field of view for their specific microscope slides. The microscope offers a full range of magnification, from 40x to 2000x.

The adjustable LED brightness is conveniently mounted beneath the table, while the microscope features an Abbe condenser with an iris diaphragm to minimize light loss and ensure precise focusing of the light beam on the observed specimen. The centering function is enabled through special screws, and the sharpness can be adjusted with a single knob. The focusing system includes both coarse and fine adjustment scales, allowing for precise control.

The table of the Levenhuk 740T microscope facilitates the observation of various sample sizes, including large specimens. To conduct detailed tests, the table can be moved along both horizontal and vertical axes, enabling researchers to precisely define their research field. Even at maximum magnification, all interesting details can be clearly observed. The table is equipped with special clamps for securely holding samples in place.

With a durable metal body, the 740T microscope ensures reliability and an extended service life. The kit also includes a dust cover for safe storage when the device is not in use for extended periods.
