Print on Demand. This book, providing an objective method of testing photographic lenses, was published in 1953 and provides photographers with two sets of charts by which the resolving power of a photographic lens may be measured and assessed against a set of predefined values. The author includes detailed instructions on the procedure and technique to be followed in order that comparable values may be obtained by different observers. This book offers an insight into the science of lens resolution and includes some ground-breaking knowledge from the field of applied optics, which had seen considerable development in the preceding decades. It is an ideal tool for anyone interested in accurately testing and rating the performance of a lens. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.…

This publication supersedes nbs Circular _533, issued May 20, 1953. It contains the original data and a new appendix describing the nbs Microcopy Resolution Test Charts No. Loloa. It provides the photographer with two sets of charts by which the resolving' power of a photographic lens may be numerically measured with respect to a definite scale of values. A detailed description is given of the procedure and technique to be followed in order that comparable values may be obtained by different observers. The test provides an objective method of testing a photographic lens. The six charts of one set are printed in black ink on a white background to form a high-contrast chart. The six charts of the other set are printed with gray ink on a gray background to form a low - contrast chart. Additional uses of these charts are also described. These uses include the testing of goggle lenses for definition and prismatic power and the testing of telescopes and binoculars for definition.
Key words: Photographic lenses; resolution test charts; resolving power.

All Forgotten Books titles are printed on demand. The moment an order is submitted, it is automatically transmitted to our distributor and then forwarded to the printer, where it enters production. This process begins within minutes and is entirely automated.
A cancellation, however, is a manual, multi-step request that must pass through several systems. By the time such a request reaches the appropriate stage, the book has almost always been printed, packed, or already dispatched, which makes cancellation impossible.
For this reason, we kindly ask that you double-check the title, edition, and your shipping details before placing an order.
If you change your mind after ordering, you are welcome to return the book once it arrives, and a refund will be issued in accordance with AbeBooks’ return policy.
