This book, as the title suggests, is about Television Optics by L.M.Myers of the Marconi's Wireless Telegraph Co. Ltd., second edition 1938. It covers both mechanical and electronic TV.
It's a pdf file of a shade over 20MB, just slightly too big to upload here, so I have zipped it and it just fits. Use WinZip or WinRAR to extract it. Linux/Unix/Mac users will know what to use for the same job.

Thanks to Harry Dalek for finding it.
WARNING: The maths could be a bit daunting for some. Even so, the photos and diagrams are worth the download.
