Applications and compatible instruments
For visual resolving-power checks and comparison of imaging systems using an established bar-chart method.
NBS 25 Resolution Target
Choose by function
What it is and what it does
The R60 pattern belongs to the NBS 25 resolution-target family. It is distinct from the NBS 1963A five-bar pattern; use the frequency and orientation layout specified for the selected artwork.
When to choose it
Choose it for five-bar reading procedures and comparisons between horizontal, vertical and oblique detail. It is particularly useful when the same recognised pattern must be compared across repeated setups.
How it differs from related products
Checkerboards, dots and grids describe image geometry. Resolution charts describe detail reproduction. A calibration workflow may need both, but they answer different questions.
What can be customised
Pattern size, feature spacing, polarity, usable field, substrate outline and mounting references can be selected around the camera and illumination. Measured geometry and traceable calibration are separate documentation requirements.
What you receive
A glass target in the selected pattern, polarity and substrate format, with the dimensional inspection or calibration records included in the order.

Common questions
Which details matter when comparing pattern variants?
Specify the exact chart layout and frequency range. NBS layouts are not interchangeable with USAF group-and-element conventions.
Selection notes
The R60 pattern belongs to the NBS 25 resolution-target family. It is distinct from the NBS 1963A five-bar pattern; use the frequency and orientation layout specified for the selected artwork.
Match this artwork reference to its labelled dimensions, polarity and active field. The product image, manufacturing artwork and inspection drawing should identify the same revision.
Information for your inquiry
Artwork reference, labelled geometry, active area, substrate outline, illumination and inspection requirements.
How do I distinguish this reference from another pattern in the same family?
Use the pattern reference and its specific geometry, labels and intended measurement. A similar outline or photograph does not establish the same frequency, coordinates or reading convention.
