The Leica S4 E with Greenough optical system and 4.8:1 zoom provides large field of view up to 36.5mm, which is ideal for inspection, assembly and repair (i.e. PCB board). The optional ErgoLenses with adjustable working distance help increase productivity, reduce fatigue related inspection errors and acquire precise positioning for specific application. Stereomicroscope eye tubes with ergonomic 38° viewing angles provide user comfort when working with basic, incident or transmitted light. The compact design is very user friendly. An optional image rotator allows easy observation of 3D specimens with a 3D specimens 45° angle, which reduces sample handling and improves inspection times.
