Optical Resolution Charts

Our Resolution Charts (Test Charts) are designed to evaluate key optical characteristics including resolution, contrast, distortion, and modulation transfer function (MTF) in lenses, cameras, and complete optical systems.

Most charts are manufactured using high-quality chrome-on-glass patterns to ensure precision and durability. For applications requiring enhanced contrast performance, selected designs are also available on Nextrema® white glass.

For thermal imaging system evaluation, we offer the R74 USAF foil test chart, specifically developed to support accurate infrared and thermal optical testing.
