USAF 1951 resolution test target
A standard bar-group pattern helps evaluate the resolving power of lenses, microscopes, and imaging equipment for fine detail.
USAF 1951 resolution targets
Custom USAF 1951 resolution test targets
USAF 1951 resolution targets for lenses, microscopes, automotive cameras, and industrial imaging systems. Transmissive or reflective formats can be confirmed by size, substrate, illumination, and reading method.
Start from the use case
Where does a USAF 1951 target fit?
USAF 1951 uses standard bar groups and elements to show the fine detail an imaging system can resolve. Selection follows the lens, working distance, illumination, test distance, and reading method rather than the chart name alone.

Technical confirmation
USAF 1951 target confirmation path
- 01
Define the test objective
Clarify whether the target compares lens resolution, checks a system limit, or supports incoming and outgoing inspection.
- 02
Choose transmissive or reflective
Match the optical mode to the light source, lens structure, and how the target is used on site.
- 03
Fix group range, size, and substrate
Use the smallest line width and test distance to set the pattern range, chart size, and substrate.
- 04
Align the reading method
Record visual inspection, capture, software analysis, packaging, and delivery requirements in one confirmation sheet.
FAQ
USAF 1951 target questions
Is a higher USAF 1951 group always better?
No. The group range should cover the useful resolving range and leave room for comparison. A pattern that is too fine may exceed the lens, distance, or lighting conditions.
Can you supply both transmissive and reflective formats?
They can be assessed against the equipment and illumination. The optical mode changes substrate, contrast, and handling requirements, so it is fixed before plate making.
Can a USAF 1951 target be used for microscope calibration?
It can support resolving-power and detail comparisons. Magnification, working distance, illumination, and reading method still need to match the microscope model.
Pattern version, dimensions, optical mode, accuracy, and delivery parameters are governed by the technical confirmation sheet.
