Automating Lab and Manufacturing Processes
For many production departments tasked with balancing manufacturing outcomes with product design requirements, the process can be cumbersome, lagged in the past by human quality control and the need to correlate results with partner tests.
Integrating image quality software with automated testing equipment in the lab and manufacturing enables maximized efficiency and enhanced quality standards throughout the development cycle.
Join us on Wednesday, March 1, 2017, for our webinar, “Automating Lab and Manufacturing Processes” to learn how to raise quality standards while maximizing efficiency.
Testing a macro lens using Checkerboard and Micro Multi-slide
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.

Color difference ellipses
Starting with Imatest 4.2, Imatest’s two-dimensional color displays— CIELAB a*b*, CIE 1931 xy chromaticity, etc.— in Multicharts, Multitest, Colorcheck, SFRplus, and eSFR ISO can display ellipses that assist in visualizing perceptual color differences. You can select between MacAdam ellipses (of historical interest), or ellipses for ΔCab (familiar but not accurate), ΔC94, and ΔC00 (recommended).

4.2 Public Beta Release, Imatest Events
Imatest version 4.2 is now available as a public beta. Join our Beta Test Group to access 4.2 updates. Highlights include:
- SFRreg Module: Analyze the SFR of slanted edges through the automatic
detection of registration mark patterns (circles with two light and two dark quadrants). Use arrays of registration mark targets to test unique imaging systems, including systems with ultra wide angle fisheye lenses (>180 degrees), multiple camera combinations, video and more.
- Point Spread Function (PSF): Imatest can now estimate an imaging system’s loss of resolution (PSF)
using a pair of collocated, near-sagittal and tangential slanted edges on SFRplus, eSFR ISO and SFRreg targets. Easily analyze and improve sharpness, chromatic aberration, and distortion measurements.
