Nexcope NE620 microscope with HDMI camera and display (DO-8601, DO-4919, DO-4930)

Modern biological microscope for advanced laboratory research
This modern biological microscope is designed for use in veterinary medicine, bacteriology, immunology, pharmacy, and many other scientific disciplines, as well as in analytical laboratories. It is equipped with a trinocular head that allows the connection of any microscope camera with a C-mount interface via an independent optical path. The trinocular tube features adjustable height, enabling precise focus matching between the camera sensor and the eyepieces.

This is the first microscope in our range to feature an infinity-corrected optical system with objectives of 60 mm optical length. This design provides a greater working distance, while the large lens diameter allows the use of eyepieces with a wider-than-standard field of view.

Optical system and image quality
The microscope is fitted with high-quality plan achromatic objectives mounted on a coded revolving nosepiece, delivering a highly detailed and sharp image suitable for demanding laboratory applications.

Stage design and ergonomics
The large mechanical stage is highly practical and user-friendly. It features concealed drive mechanisms and moves relative to the stand only along the Y axis, saving valuable space on both sides of the microscope. The stage holder allows two slides to be mounted simultaneously, making quick comparison of specimens easy and efficient.

Illumination and observation comfort
LED illumination provides high brightness and long service life. Unlike halogen lamps, LED light sources generate significantly less heat, which is especially important during long, uninterrupted observation sessions. The microscope is equipped with automated illumination that adjusts light intensity to the currently selected objective, while still allowing manual brightness control.

A built-in field diaphragm in the illuminator enables proper Köhler illumination, ensuring maximum resolution, brightness, and contrast, particularly at high magnifications.
