Vertical Optical Comparator – QualiPP™ IV

The QualiPP™ IV Vertical Optical Comparator delivers fast, one-touch 2D flash measurement for quality laboratories and production environments. Equipped with a 20 MP camera and dual telecentric optics, the IVP-100 captures the complete measuring field in a single image and automatically calculates part dimensions from the projected silhouette. This non-contact optical measurement method provides the speed of automated vision inspection while eliminating fixture setup and manual screen-overlay procedures associated with traditional profile projectors.

Designed for electronics, machined components, automotive parts, and medical device manufacturing, the IVP-100 is well suited to high-mix production environments where frequent product changeovers require fast and consistent inspection. Its automated measurement workflow helps quality teams reduce inspection time while maintaining reliable dimensional results.

The QualiPP™ IV model IVP-100 features a compact 366 × 425 × 665 mm footprint and weighs 30 kg, making it easy to position on a laboratory bench or near a production workstation. A 15.6-inch touchscreen provides a clear view of the live camera image, measurement results, and saved part programs. The system includes four USB ports and one LAN port for data transfer, factory network connectivity, and integration with quality reporting systems. Designed for 24-hour continuous operation, the IVP-100 supports demanding production schedules and shift-based inspection requirements.

Quality-control teams can use the vertical optical comparator to speed up first-article inspection, in-process inspection, and dimensional quality control. The system automatically identifies parts and loads the appropriate measurement program, reducing the need for manual program selection and file management. New measurement programs can be created or adjusted directly on the touchscreen by sketching measurement elements with a finger, helping shorten setup time for new components.

At the end of each measurement cycle, the IVP-100 can automatically generate inspection reports, reducing manual data entry and simplifying the transfer of measurement results to quality management and reporting systems. With automated optical measurement, telecentric imaging, touchscreen operation, and fast program selection, the QualiPP™ IV Vertical Optical Comparator provides an efficient solution for high-volume and high-mix dimensional inspection.

Vertical Optical Comparator

  • Compact Desktop Design: With a 366 × 425 × 665 mm footprint and 30 kg weight, the IVP-100 fits on standard laboratory benches and can be positioned close to production areas without requiring a dedicated metrology room or floor-mounted system.

  • One-Touch Measurement Start: After placing the component on the measuring stage, operators can start a complete inspection cycle with a single touch, helping reduce routine measurement time to seconds.

  • Dual Telecentric Optics with 115 × 75 × 30 mm Measuring Volume: The dual telecentric optical system maintains consistent magnification throughout the measuring field, minimizing perspective-related dimensional errors for components up to 30 mm in height.

  • Dual LED Illumination: Independent green contour and white ring lighting provide flexible illumination for edge and surface measurements, producing high-contrast images across different materials, shapes, and surface finishes.

  • Intelligent Automatic Feature Recognition: The software automatically analyzes captured images and identifies geometric features, reducing manual point selection during routine dimensional inspections.

  • 15.6-Inch Touchscreen Interface: Operators can create measurement elements directly on the touchscreen using finger gestures, simplifying program creation and reducing the learning curve for new users.

  • Fixture-Free Part Placement: Components can be positioned anywhere within the 135 × 95 mm stage glass area without dedicated jigs or alignment fixtures. This helps minimize setup and changeover time between different part numbers.

  • Automatic Edge Detection and Boundary Filtering: Advanced image processing identifies component edges while filtering surface clutter and boundary noise, supporting consistent measurements on irregular or reflective parts.

  • Automatic Program Recall and Report Output: The system can identify the inspected part, recall its stored measurement program, perform the inspection, and generate a measurement report without requiring manual file selection or repetitive data entry.

  • 24-Hour Continuous Operation: The IVP-100 is designed for extended operating schedules, making it suitable for shift-based manufacturing, high-volume inspection, and production environments requiring continuous dimensional measurement.

  • Touch-Based Program Editing: Technicians can create, modify, and optimize measurement programs directly from the touchscreen, allowing inspection routines to be adjusted without a keyboard or external programming equipment.

Theory and Measurement Method

The QualiPP™ IV Vertical Optical Comparator uses transmitted contour illumination to produce a high-contrast shadowgraph of the component under inspection. A green LED light source positioned beneath the measuring stage directs light through the glass platform and the part profile. Areas blocked by the component appear as a dark silhouette, while unobstructed areas remain bright. This distinct contrast creates a clearly defined boundary for the image-processing system to detect and measure.

The dual-axis telecentric optical system is central to the IVP-100's image-based measurement method. Telecentric optics maintain parallel principal rays along the optical axis, keeping image magnification consistent across the specified depth of field. This minimizes perspective-related dimensional errors commonly associated with conventional imaging lenses, where changes in component height can affect apparent size.

With this optical configuration, the IVP-100 delivers measurement accuracy of ±8 μm and repeatability of 5 μm across its 115 × 75 mm measuring field. Consistent magnification helps provide stable dimensional results across different component positions within the measurement area.

The system captures the complete 115 × 75 mm measuring field in a single image, which is the core principle behind flash measurement. Its 20 MP camera records the full component silhouette in one image pass, while advanced edge-detection software identifies geometric features such as circles, lines, arcs, and angles for automated dimensional analysis.

A white LED ring light complements the green contour illumination when inspecting components with reflective or visible surface features. This dual-lighting configuration provides greater flexibility for different part geometries, materials, and inspection requirements.

Once the system identifies a stored component, the IVP-100 automatically recalls the associated measurement program, performs the programmed inspection, and generates the measurement report. This streamlined workflow reduces manual program selection and supports fast, repeatable dimensional inspection.
