– Key Features
The stereo body (SV 8) accepts modular objective and eyepiece configurations, allowing users to tailor magnification and working distance to specific applications. The Greenough optical path provides natural depth perception without chromatic aberration artifacts inherent to monocular designs. Fine focus adjustment enables precise image acquisition across the working range.
– Typical Applications
Stereo microscopy for material inspection, microcircuit examination, entomological specimen study, jewelry and gemstone evaluation, and precision assembly work where depth perception enhances defect detection.
– Compatibility & Integration
This stereo body integrates with Zeiss paired-objective sets and standard eyepieces. Mounting to table stands with 32 mm column supports is standard. Illumination systems—both incident and transmitted—attach via lamp socket provisions. AS IS condition indicates component completeness and functional state vary by unit; physical inspection recommended prior to integration into optical systems.
