About This Webinar
The technical data sheet, the most basic form of communication about lens specifications in the industry, should provide an objective and uniform key to helping buyers compare lenses and understand the basic tolerances associated with data sheets and ISO standards, but it does not. Data sheets can be very misleading from optical company to optical company. The comparisons are not apples to apples because the format and the data presented in data sheets are not held to an international standard and are not overseen by a governing body. Additionally, even when certain lens parameters within a data sheet are tied to an ISO standard, the standards themselves are poorly understood by the engineering community.

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. 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.

Who should attend:
Optical engineers and all those working with optics who are interested in gaining a further understanding of COTS lens tolerances. Engineers, researchers, and R&D scientists who work with optical design, lens selection, cameras, machine vision, microscopy, and astronomy. Professionals who purchase lenses and optical components.
