The MTF Star System with MTF Star Sensor, MTF Star Software<br />
and MTF Star Test Chart from Chrosziel and IB/E were accorded<br />
much attention at Cinec, and awarded a Cinec 2010 Prize. The<br />
system is an innovative way to analyze the optical performance<br />
of a lens by measuring its contrast transmission (Modulation<br />
Transfer Function) using any existing Chrosziel lens projector.<br />
Developed by Chrosziel in conjunction with IB/E Optics, the<br />
MTF Star System consists of an electronic sensor that attaches to<br />
a computer. Hold it against the surface onto which you normally<br />
project your lens tests, and view the results as pictures, graphs<br />
and tables. Data can be saved for future reference, shared with<br />
colleagues as PDF files, printed and kept with the lens, or used<br />
for presentation and comparison. No more counting line pairs<br />
or subjective interpretation. The MTF Star Software displays the<br />
picture being measured, the MTF value of the position selected<br />
on the graph, and the reference resolution as a percentage.<br />
