• Tests Resolutions from 4 to 228 lp/mm
• Ability to Test Multiple Field of Points Using 9 Targets
• Reduces Testing Time
The USAF pattern wheel is an ideal target to measure resolution at different field points within an imaging
system’s field of view. The pattern is available on three different substrate sizes: 1" square, 1,5" diameter, or a
1" x 3" slide. Each size includes 8 USAF patterns in a circular pattern plus one pattern in the center. Each size
is offered as positive (opaque pattern on clear background) or negative (clear pattern on opaque background).
No. of USAF Patterns: 9
Line Width Tolerance: ±0,0005 mm
Substrate: Float Glass 1,5 mm thick
Flatness: inch
Minimum Resolution: 2λ/Group: 2 Element: 1 (4 lp/mm)
Surface Quality: 20-10
Maximum Resolution: Group: 7 Element: 6 (228 lp/mm)
Parallelism: < 0,0005"/inch
Coating: First Surface Reflective Chromium

• Negative or Positive Patterns (≥ 3,0 OD Chromium Coating)
• Complies With NBS Standard 1010A
• Frequency Range From 1-512 Cycles/mm
Utilizing the National Bureau of Standards 1963A Resolution Pattern, these targets - available in either positive
(black pattern, clear field) or negative (clear pattern, black field) and on float glass or opal glass, are ideal
for precision optical testing.
