The eBooks on the SPIE Digital Library are available only to users from institutions with eBooks subscriptions. Individuals who are not affiliated with subscribing institutions may instead purchase eBooks on SPIE.org here; click any title to select among the available formats.

For more information, see About the SPIE Digital Library.

For ebooks in the Field Guide series and the Spotlight Series, users can download the entire ebook as a PDF. These ebooks tend to be short, with a small file size.

For ebooks in the Press Monograph series and Tutorial Text series, the ability to download the entire ebook as a PDF is not currently supported, so the chapters must be individually downloaded.

Please note that the ability to download ebook content from the SPIE Digital Library is available only to users from institutions with ebooks subscriptions. Individuals who are not affiliated with subscribing institutions may instead purchase ebooks on SPIE.org here; click any title to select among the available print and electronic formats.

The "Open Access" icon  means that the author of the paper paid for it to be accessible to everyone in order to promote knowledge transfer, education, and awareness of technology and industry developments in optics and photonics. A subscription is not required to download an article marked Open Access. To find out more about Open Access publications from SPIE, please click here.

Front Matter for older (2001 and earlier) volumes has not been digitized and published on the SPIE Digital Library. This material may be added in the future.

SPIE's Milestone Series is not available on the SPIE Digital Library. You can view the full list of Milestones and purchase print volumes on the SPIE.org website here.

Some Proceedings volumes are not available in the SPIE Digital Library due to conference cancellation or lack of electronic publishing rights. Please see Proceedings Volumes Not Available Online for a list of these volumes and more information. 

SPIE Journals and Proceedings use six-digit citation identifiers (CIDs) in place of traditional page numbering. This allows us to build an online journal issue or proceedings volume one article or paper at a time, while retaining the ability to segment tables of contents by paper type or subject area. 

In the SPIE Digital Library, an article-level page displays the CID in the metadata at the top of the page beneath the authors' names, and in the citation at the bottom of the page.

You can read more about how to cite papers using CIDs on the citation format page.

To find the publication date of record for a Journal article or Conference Proceeding paper, navigate to that article's page and note the date above the title. The date is also included within the paper's citation, which appears at the very bottom of the page.

For Conference Proceedings, please note that the dates at the top of the volume's Table of Contents page indicate the first and last days of that conference -- not the publication date of the papers within that volume. The date within the individual paper's citation is the publication date of record, being the date that the manuscript was published on the SPIE Digital Library.

If an article has been cited, then the article page will include a tab labelled "Cited by" which contains information about other works that have cited the article.
