The E3 features a PL10X/18mm large field eyepiece for a wider view and comfortable observation. It can be paired with a professional flat-field achromatic objective for sharp images and true colors, immersing students in the microscopic world.

The E3 biological microscope features a compact, rigid body that considers the physiological characteristics of users. Its hollowed-out arm design is lightweight and flexible, with the hollow sections serving as hand grips for easy one-handed transport.

The base of the microscope has a built-in rechargeable module for power and battery charging. With long battery life, it handles power outages and outdoor use, making it ideal for fieldwork. A charging indicator lamp shows battery status at a glance.

The microscope's back panel features a cable management system that effectively stores excess power cables when not in use, improving laboratory tidiness and reducing trip hazards during transport. The E3 uses a USB charging cable, allowing for convenient power supply from computers or power banks.

The digital model features a built-in integrated digital observation head, allowing images captured under the microscope to be wirelessly transmitted in high definition to a display. It can also share the images via a wireless network to external tablets and smartphones, enabling simultaneous preview observations on multiple devices.
