SFRPlus Chart measurable parameters: MTF, lateral chromatic aberration, distortion, color accuracy, tone response, white balance, noise, gamma

SFRplus清晰度测试卡

SFRPlus Chart Features：

1. Compared with the ISO 12233 chart, the SFRpuls test chart makes full use of the chart space and has a large amount of information
2. More information is helpful for analyzing signal processing, such as noise reduction and sharpening
3. Support fully automatic selection
4. Avoidance of tone overflow caused by high contrast, increased exposure latitude, and higher accuracy and repeatability
5. Support a variety of sizes and materials (matte, matte)

Product parameter introduction:：

Parameter	SFRplus 5X9 Large chart (4:1)
Size	111.76cm x 152.4（43.6“×60”）
Contrast	4: 1 and ISO12233: 2014 standard compliance
Measurable parameters	MTF, lateral chromatic aberration, distortion, color accuracy, tone response, white balance, noise, gamma
Material	Matte light: suitable for conventional camera detection, with higher maximum density and more details, but because of surface reflection, it is not recommended for wide-angle lens detection Matte: It is recommended to test most lenses, the surface reflection is relatively uniform, the mirror reflection is very little, and its MTF extreme value is less than the matte MTF extreme value
Resolution	The inkjet printed test card can reach 5cycle/mm of MTF50. Based on this, the small size of the test card will reduce the MTF value of the high-resolution camera system to the limit MTF value. The size of the card should be selected to meet the minimum focus distance of the camera. , The resolution is greater than the resolution of the sensor
