The Nexcope NE620 compound microscope is an excellent quality workhorse microscope. It offers very high optical performance in at a very affordable price.

Clever Ergonomic Features

Front

Automatic Brightness Switching

One of the stand out features of the NE620 is the automatic brightness control. When the operator changes objectives, the intelligent controller switches the brightness to the last used setting.

Automatic Sleep Timer

The illumination controller also allows for a sleep timer that turns the LED illumination off after a set period.

Excellent Optical Design

Objectives

NIS Infinity Optical System

The NE620 comes with NIS65 infinity plan achromat objectives and 10x eyepieces with a wide 22mm field of view. Infinity optical systems allow for more colour correction and the easy addition of additional contrast techniques.

Quality Plan Achromat Objectives

Nexcope objectives offer clear, bright and flat images. In addition to the standard 4×, and 10×, objectives, the 40× has a long 1.5mm working distance, and 100× objectives are available in oil or water immersion versions.
