Assembly verification
Place alignment, scale and resolution regions on one plate for repeated checks at defined positions.
Multi-Feature Imaging Test Targets
Several checks in one glass target.
Combined imaging targets bring several reference geometries onto one substrate for multi-step focus, alignment, scale and image-quality workflows. Each region has its own measurement purpose.
Product selection
What it is and what it does
A multi-feature target combines selected bars, dots, edges, apertures or alignment marks on one part. It reduces target changes when an inspection station performs several checks in sequence. The visible reference patterns must still be matched to the software and illumination used for each check.
When to choose it
Start with a list of measurement outputs, then assign one region and acceptance method to each. A clear circular feature may be an optical aperture or a geometric reference; a patterned film opening is not necessarily a hole drilled through the glass.
Combine the checks used by your instrument
Method-specific analysis
Each region needs its own reading rule. The combined target does not turn a geometric grid into an MTF feature.
Assign a role to every pattern region
| Choice | Selection basis |
|---|---|
| Test functions | Choose the required checks first, then the matching bars, edges, grids or registration marks. |
| Shared coordinate system | Define the relationship between regions and the mounting datum. |
| Field and illumination | Keep each functional region resolvable under the intended optics and lighting. |
Formats and pattern options
Combined imaging pattern
Dimensions to drawing
Multiple shapes and alignment references on one substrate.
Circular-feature and alignment pattern
64 mm plate
Unequal circular features and fiducials; not a regular dot array.
Circular references and alignment marks
Custom layout to drawing
Circular features, crosshairs and a scale share one field. Define coordinates and the function of each region in the approved drawing.
Where this product is used
Combine scale, alignment and detail checks in one fixture.
Inspection and delivery
Inspect each functional region against its own dimensions and defects, then verify registration between regions and the substrate datum. Identify any report values as nominal or measured.
A combined patterned glass target is supplied with identified functional regions and their shared reference system. Inspection covers each region’s geometry and their relative positions.
Selection notes
Multi-feature targets combine several reference patterns on one substrate for imaging inspection.
Assign each region a task: resolution, scale, alignment, distortion or contrast. Keep coordinates and analysis settings linked to the correct region.
Information for your inquiry
Pattern list, region coordinates, frequency or pitch, active area, polarity and substrate.
Does one combined target produce every calibration result?
Each pattern needs the corresponding capture and analysis method. Combining regions does not make their measurements interchangeable.
