For Quality that Lasts
Leica EZ4 StereoZoom® and EZ4 D (Documentation)
Stereomicroscopes for Assembly, Inspection, and Quality Control
Dependable and Rugged for
Industry and Routine Research
Introducing the Leica E Series StereoZoom® Systems
Leica Microsystems presents four affordable stereomicroscopes featuring renowned Leica
StereoZoom® performance for industrial quality control and routine laboratory applications.
• Leica EZ4 with fixed 10× eyepieces
• Leica EZ4 with fixed 16× eyepieces
• Leica EZ4 with open eyetubes (optional eyepiece selection)
• Leica EZ4 D with integrated digital camera and free LAS (Leica Application Software)
Manufacturers depend on affordable and reliable quality control to insure production profitability.
Oxidation location on a sample Visual quality control is an important part of a consistent quality management process. The Leica
E Series is designed to help you eliminate expensive quality defects, waste, and insufficient produc-
tivity. For R&D, the dependable, maintenance-free Leica E Series ensures efficient laboratory oper-
ations while minimizing downtime. Providing a bright object field that is rich in detail and a great
working distance that allows a variety of microscope tools, the Leica E Series is ideal for sample
identification and sorting.
Benefits at a Glance:
• The Leica E Series features a 4.4:1 zoom range.
• The complete product line for quality assurance includes a model for digital documentation
(Leica EZ4 D) and measurements (Leica EZ4, optional eyepiece selection).
• Features high-quality image, color, and detail fidelity.
