Optical stereo microscope SMZ745

inspectionfor materials researchindustrial

Overview
The SMZ745T (trinocular) and SMZ745 stereo microscopes provide a 7.5:1 optical zoom ratio and a standard working distance of 115 mm. They are intended for materials research and production-line industrial inspection, enabling both stereo visual inspection and digital imaging (SMZ745T).

Applications

• Failure analysis and verification of failure modes
• Component surface inspection, crack detection and corrosion studies
• Inspection of composite materials and textiles
• Examination of machined parts for aerospace, construction and other industrial applications

Optical heads and imaging
SMZ745T: trinocular head with an integrated camera port (0.55x C‑mount) compatible with 2/3 in. or smaller CCD for digital imaging while retaining stereo viewing. SMZ745: binocular head offering the same optical performance and working distance. Both are compatible with a range of eyepieces and auxiliary objectives to adjust magnification and working distance.

Key features

• 7.5:1 optical zoom ratio for continuous magnification selection
• Standard 115 mm working distance (before using auxiliary objectives)
• Greenough optical system for stereoscopic observation
• Robust functional design with special surface treatments
• Air-tight body joints (SMZ745) to reduce internal contamination
• ESD protective coating to reduce electrostatic risk to samples
• Anti-mold internal coating for humid environments
• Five auxiliary objectives available to extend magnification and working-distance options
