Product Details:

Measurable parameters

1. MTF
2. Lateral chromatic aberration
3. Distortion
4. Color accuracy
5. Tonal response
6. White balance
7. Noise
8. Gamma

Features

1. Make full use of the space of the chart card, and the amount of information is large. Compared with the actual utilization rate of the ISO12233 test card, the actual utilization rate is only 10%, which is greatly improved.
2. More information is helpful for analyzing signal processing, such as noise reduction and sharpening
3. Fully automatic selection
4. Avoidance of tone overflow caused by high contrast, increased exposure latitude, and higher accuracy and repeatability
5. Support multiple sizes and materials

Material

1. Matte: suitable for conventional lens testing, the maximum density is larger, and the details are more, but because of the surface reflection, it is not recommended for the detection of wide-angle lenses
2. Dead lustre: 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

	Transmissive	Reflective
Inkjet printing	NO	YES
Silver salt photo paper	NO	YES
Film material	YES	NO
Chrome-plated glass material (highest precision required)	YES	NO

Contrast

1. 4:1 and ISO12233:2014 standards meet
2. 2:1 and 10:1 can analyze nonlinear tone response

Size

Chart size	5x9 (suitable for SLR cameras with an aspect ratio of 3:2 (DSLR format) and 16:9 HDTV format)	5x7 (suitable for card cameras and mobile phones)
Extra small	8.5“×15”	8.5“×10”
Small	14“×24”	14“×20”
Medium	24“×40”	24“×34”
large	44“×60”	44“×60”
Extra large	44“×74”	44“×64”

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.
