Chrome on Glass Checkerboard Targets
The Chrome on Glass Checkerboard Test Chart is designed to work with the Checkerboard module. This module enhances testing of varying distances by supplying more testable regions to provide automated measurements of sharpness, lateral chromatic aberration, and distortion from images. The Checkerboard target covers the visible and NIR spectrum. The chart is also available on other substrates.
For ease of placement and removal, options include an acrylic frame sized for Imatest LED Lightboxes size B through D and Light Panels size A through D.
