Imatest is pleased to unveil updated documentation for Imatest IT. The documentation has been updated to include the latest software release (Imatest 4.5), including details for new features, filtering options for preferred languages, and several new Troubleshooting articles. (more…)
Imatest’s charts and software allow you to measure the characteristics and parameters of imaging systems. Quite often these measurements simply indicate the limits of system performance and expected image quality.
But some Imatest results let you improve image quality— and subsequent images taken by the same system— by correcting measured aberrations. (more…)

Light Source
The most uniform light source available would be an integrating sphere, but these come with considerable size and expense. After considering how the light source uniformity impacts their results, most lab & manufacturing tests use LED or fluorescent lightboxes with flat-panel diffusers. (more…)
Testing a 1-5x Macro Canon MP‑E 65mm Lens
Imatest’s Checkerboard module is our new flagship module for automated analysis of sharpness, distortion and chromatic aberration from a checkerboard (AKA chessboard) pattern. The big benefit of using the checkerboard is that there are looser framing requirements than with other kinds of test targets. While checkerboard lacks the color and tone analysis provided by SFRplus and eSFR ISO, these features are not available on the high precision chrome on glass substrate, so the checkerboard is the optimal pattern for this test.
