Nexcope NE610 microscope (DO-8600)

Modern biological microscope for scientific and laboratory research
This modern biological microscope is designed for use in veterinary medicine, bacteriology, immunology, pharmacy, and other scientific fields, as well as in analytical laboratories. It is equipped with a trinocular head that allows any microscope camera with a C-mount to be connected via an independent optical path. The trinocular tube features height adjustment, enabling precise focus alignment between the camera sensor and the eyepieces. The microscope uses an infinity-corrected optical system with precise coarse and fine focusing and a wide eyepiece field of view of up to 22 mm.

Optics and image quality
The instrument is fitted with high-quality plan achromatic objectives that provide a highly detailed image. The 40× objective features an extended working distance of 1.5 mm, which helps prevent accidental contamination when working with immersion liquids.

Stage design and user comfort
The large mechanical stage is 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 slide holder allows two specimens to be mounted simultaneously, enabling fast and convenient comparison.

LED illumination
LED illumination provides high brightness and long service life. LED light sources generate significantly less heat than halogen lamps, making them particularly suitable for long, uninterrupted observation sessions.

Expandable observation techniques
The microscope supports a wide range of optional accessories, enabling advanced observation techniques such as dark-field observation and simple polarization.
