Detail Information상품 상세 정보SKU: SPIJ4The SFRplus test chart can be used with the SFRplus module in Imatest 3.2 or later to measure MTF, lateral chromatic aberration, distortion, tonal response, and color accuracy. The SFRplus module features fully automated region-of-interest detection. The SFRplus chart offers significant advantages over commonly used charts such as the ISO 12233 chart, including:
DetailsVideo (Watch on our site)SFRplus options are offered to support a wide range of image testing applications. Options include: Contrast Ratios Options
Paper Type - Semi-gloss or Matte Options
Square Grid Dimensions Options
Ink Jet Chart ResolutionThis chart, and all our ink jet printed charts have an approximate MTF50 of 5 cycles/mm. For a comparison of rflective surfaces, as well as what this means when choosing your chart, please visit our Reflective Surface Comparison Blog. 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. Paper Size and Active Area OptionsCharts are available in five 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. Paper Size (Including Margin)
Active Area The 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 SFRplus software.
Color Chart OptionsInclusion of the color chart enables testing of color accuracy. If the color option is selected, the "focus star" pattern that aides in focusing is replaced by a 20 patch color chart. Pre-Distortion OptionsPre-distorted charts offer the ability to map the outer edges of a wide angle or fisheye lens using SFRplus. These distortion levels are available
We do not recommend using semi-gloss paper for wide angle lenses or pre-distorted charts Custom variations of the SFRplus chart are available. Please contact sales@imatest.com to discuss your specific requirements. DNC Mall User Guide디앤씨몰 이용안내![]() Related Products관련 상품
