Putora Sharpness Indicator Field Chart A10 (7A10)

The new Putora A10 (7A10) Sharpness Indicator model is the most advanced and accurate test chart available! This new test chart allows working with the most advanced lenses, achieving a resolution of up to 130 lines per millimeter in the basic capture mode of the test.

You will be able to accurately evaluate the sharpness and resolution of all types of film, video and camera.

The sharpness indicator consists of test targets with concentric circles printed on the background at the level of the reference field. The background has the same reflectivity as the average reflectivity of the targets. When the target appears to blend into the background, the table shows that the target is out of focus of the system under test.
