R70 USAF 1951 Test Chart

The optical resolution charts are used to test characteristics such as resolution, contrast, distortion and modulation transfer function (MTF) of lenses, cameras and optical systems. Ronchi rulings and grids are used to create interference patterns, to measure distortion and for MTF measurements.

EMS offers a range of charts on glass and in metal foil. Customers often require special charts for specific applications and these can be made to your exact requirements.

In addition to these products, we also supply a specialist NPL/HSE test slide for checking the resolving power of phase contrast microscopes – please see ref S84 in stage micrometers.
