 Let we understand the depth of field: If you focus a lens on a subject, only that subject is theoretically 'perfectly' in focus. A black line painted on a white wall will be perfectly focused if the image projected on the back of your eye has no light striking on one area (the black part of the image), and the area immediately next to it will have white light striking it. As you look at other distances closer, or further away, they are slightly out of focus. Your eye's image will see black in one area, and white in another area, but there will be a blurry grey line between the two where the light goes from black to white. However, if the degree of fuzziness (circle of confusion) around a subject is smaller than your eye's ability to see (generally considered to be about 1 arc minute), your eye will think the subject is in focus. There is therefore actually a distance in front of and behind your subject which will appear to be in focus. Hence, 'perfect focus' for a lens is not really 1 precise theoretical distance, but a range, called your Depth of Field. Note in the picture above, the focal point is on the word 'depth', however the lines above and below it are still in good focus.
Test Depth of Field of Your Imaging System.
Effective Measurement Eliminates the Need for Calculations.
This unique target was developed to standardize an area of optical tolerancing that is most commonly determined theoretically. Our extensive experience in designing optical systems has shown that depth of field calculations can often yield very misleading results. This target solves the problem and very accurately determines the amount of shift an object can undertake before producing an unacceptable image. The definition of what constitutes an acceptable image is determined by the user and the application.
The Depth of Field 5-15 is made up of two sets of scales. Each, when viewed at 45°, consists of horizontal and vertical lines at a frequency of 5 and 15 line pairs per mm.
The depth of field plate method of use:
