improves ability to analyze non-linear signal processing, which may not
affect the lower contrast 2:1 contrast ratio regions
contrast only improves the completeness of 3D maps of
performance across the imaging surface.
contrast ratio matches the upcoming new ISO-12233 specs.

Type - Semi-gloss or Matte Options
paper can be easier to light because it has less specular
reflection than the semi-gloss paper. The MTF is slightly
less than semi-gloss paper and does not have as deep dark tones on the
paper has slightly higher detail than matte, has deeper black
tones on the stepchart, and is recommended for most applications except
for wide-angle lenses.
Grid Dimension Options
grid dimension is recommended for for typical DSLR formats
with aspect ratios of 3:2 and typical HDTV formats with aspect ratios
grid dimension is recommended for typical compact
camera formats with aspect ratios of 4:3.
Jet Chart Resolution
chart, and all our ink jet printed charts have an approximate MTF50 of
5 cycles/mm. Please keep this in mind when choosing the size
of chart. Using a chart that is too small with a
high-resolution sensor can result in the MTF of the chart degrading the
measured MTF of the camera system. In addition, it is important to use
a chart that is large enough to accomodate the minimum focus distance,
as well as the resultion of your sensor.
Size and Active Area Options
are available in tfive main sizes with variations depending on the grid
dimensions selected. It is recommended that the medium sized charts be
used to test imaging systems with sensors up to 12 MP, the large charts
be used for testing of sensors above 12 MP and up to approximately 24
MP, and the extra-large charts be used for sensor sizes above 24 MP.

active area of the chart includes white space above and below the top
and bottom distortion bars. It is slightly larger than the printed
area, which is bounded by the distortion bars on top and bottom. White
space is included in active area because test images of the chart must
include this white space in order to enable automated processing in

option is selected, the "focus star" pattern that aides in focusing is
replaced by a 20 patch color chart.
charts offer the ability to map the outer edges of a wide angle or
fisheye lens using SFRplus. These distortion levels are available
