The Unitron ZSB binocular microscope head is a dual-eyepiece optical component engineered for integration into Unitron microscope systems. It delivers enhanced viewing comfort and extended magnification capability across laboratory, research, and educational applications through a parfocal twin-zooming objective system paired with interchangeable eyepieces and auxiliary magnification lenses.
Technical Specifications
Optical Design & Magnification

– Key Features
• Binocular optical path for reduced operator fatigue during extended observation sessions
• Parfocal objective design maintains focus across the 0.7x to 4.5x magnification range without refocusing
• Modular auxiliary lens system permits working distance optimization for varied specimen types
• High-resolution flat-field optics minimize chromatic aberration and edge distortion
– Typical Applications
• Material science and metallographic specimen examination
• Biological and histological sample analysis
• Quality control and failure analysis in manufacturing environments
• Educational microscopy in academic laboratory settings
• Precision inspection requiring magnification flexibility and extended working distances
– Compatibility & Integration
Designed as a replacement or upgrade head for existing Unitron microscope systems. Note: This model was discontinued in 2009; availability of replacement parts and accessories through Unitron should be verified with the manufacturer.
