Understanding MTF Data Sheets Across Manufacturers
Compare the data sheets from Japanese, German, and U.S. lens manufacturers side by side. They have almost nothing in common. But the problem isn’t rooted in cross-cultural issues. Compare data sheets from three lens makers in the same country, and the result is the same. Each company uses its own format and nomenclature. Each company essentially is reinventing the wheel, but it is the buyer of the lens who faces the prospect of misinformation.
What Optical Engineers Should Look for in Lens Specifications
In order to help optical engineers and system designers view lens data sheets more critically, better circumvent traps hidden within, and ask the right questions of lens providers, they must focus on the following key data sheet information and their associated tolerances or lack of actual tolerances with respect to the data sheet being viewed.
