Converging-light stereo scopes distort the view toward the edges of the field. The INSIZE ISM-ZS200 uses a parallel optical path to keep the whole 0.8X–8X field clear and low-distortion for accurate 3D inspection.
A parallel-light stereo microscope for low-distortion inspection
Professional Parallel-Light Stereo Inspection
The INSIZE ISM-ZS200 Parallel Light Stereo Microscope is a professional optical inspection system designed for detailed three-dimensional observation, component inspection, assembly work, and precision quality-control applications. Its infinity parallel optical system provides a stable optical path while the 20° inclined binocular viewing tube improves viewing ergonomics during extended inspection sessions.
With a 0.8X–8X continuously variable zoom objective, the ISM-ZS200 provides a 10:1 zoom ratio, allowing users to move from a wider field of view to detailed inspection without changing the primary optical configuration.
The system also supports advanced illumination options, including optional coaxial illumination for deep holes and recessed features and an optional aperture diaphragm for increased depth of field and improved image quality.
Key Features
Infinity Parallel Optical System
The ISM-ZS200 uses an infinity parallel optical system designed to provide a consistent optical path while allowing accessories to be incorporated into the system.
This configuration is particularly useful for professional inspection environments where optical flexibility and image quality are important.
10:1 Zoom Range
The 0.8X–8X zoom objective provides a 10:1 zoom ratio, giving inspectors a broad range of magnification without requiring frequent objective changes.
This makes the microscope suitable for both general inspection and detailed examination of small features.
Ergonomic 20° Inclined Viewing Tube
The binocular optical tube is inclined at 20°, helping create a more comfortable viewing position for prolonged inspection and reducing the need to maintain a steep downward viewing angle.
Wide-Field 10X Eyepieces
The standard 10X wide-field eyepieces provide a Ø22 mm field of view, giving the operator a useful inspection area while maintaining detailed optical observation.
Adjustable Reflected & Transmitted LED Illumination
Integrated adjustable LED illumination supports both:
The ability to control illumination helps improve contrast across different workpiece surfaces and geometries.
Optional Coaxial Illumination
Coaxial illumination can be added when inspecting deep holes, recessed features, or areas that are difficult to illuminate effectively with conventional ring-style lighting.
This provides additional flexibility for specialized inspection applications.
Optional Aperture Diaphragm
An optional aperture diaphragm can be used when greater depth of field and image quality are required for particular inspection tasks.
