Digital stereo microscope EZ4 W

opticaleducationfor biology

Overview
The Leica EZ4 W and EZ4 E are educational stereo microscopes designed for college and university science classrooms. They include an integrated 5‑megapixel camera for HD live streaming to students' devices and support multiple connection modes for flexible classroom deployment.

Key Features

• Focusing drive: Adjustable ease of movement for comfortable focusing by students and instructors.
• LED incident light: Independently switchable or combined illumination; controlled via CapSense membrane panel.
• Vibration‑resistant feet: Transparent rubber feet reduce shake and protect tabletops.
• CapSense control panel: Durable membrane controls for intuitive operation and easy cleaning.
• Ergonomic viewing: 60° viewing angle; eyepiece tubes adjust simultaneously from 50 to 75 mm for correct interpupillary distance.
• Zoom: 4.4× zoom providing 8× to 35× magnification for detailed observation.
• Optical system: 10° Greenough design delivering a flat field, large depth of field and 3D perception.

AirTeach & Teaching Tools
AirTeach classroom software enables teacher-led interaction: instructors can view thumbnail layouts of students' microscope images, display up to four images side‑by‑side for comparison, and confirm camera logins to manage participation.

Leica AirLab App (mobile)
The Leica AirLab mobile app offers touch-based control for students and instructors: camera setup, image capture, annotation, measurement, archiving and sharing. The built‑in camera is accessible from Wi‑Fi enabled PCs, Macs, tablets and smartphones; HDMI output supports projection to large screens.

Camera, Connectivity & Documentation

• Integrated 5‑megapixel camera powered and controlled directly from the microscope.
• EZ4 W: supports internal Wi‑Fi streaming and optional connection via facility network.
• EZ4 E: connects exclusively via the facility network (WLAN or LAN) to avoid creating additional Wi‑Fi access points.
• Ethernet mode: connect camera through facility network to support many simultaneous users on the same network.
• USB mode: direct PC connection via USB for fastest live images, useful for moving samples.
• Capture options: record to SD card or connect to Leica Application Suite (PC) / Leica Acquire (Mac) for acquisition and processing.
• HDMI output: connect to HD monitors or projection systems.

LED Illumination
Powerful 7‑way LED system provides homogeneous, color‑neutral incident and transmitted illumination. Modes include incident, oblique and transmitted light to optimize contrast for diverse samples. LEDs are maintenance‑free and energy efficient.

Education & Learning Outcomes
Designed for higher education, the EZ4 series supports practical microscopy skills development. Students will:

• Sharpen observation and documentation skills.
• Examine, compare and identify structures in plants and organisms.
• Explore evolution, behavior and biological diversity.
• Integrate field and laboratory observations with classroom theory.
• Develop awareness of ecological relationships and environmental issues.

Operational & Practical Benefits
Easy setup and dismantling; single power cable per unit. Rugged design suitable for classrooms, routine research and quality control with low maintenance and long service life.
