Mission:
This database was created to help people to find information about special large format (big diameter) objective lenses, achromatic and apochromatic (APO) doublets, triplets, and quadruplets, which are not just condensors, having relatively fast focal ratios. These giant lenses can be effectively used in extremely fast telescopes (with relatively small magnifications) in huge binoculars, and TV/HDTV movie projectors. The original function of these very big optics usually used to be projection lenses utilized mainly in episcopes (epidiascope, or episkop).
The images and the data are mainly gathered from ebay (www.ebay.de, photo.ebay.de, photography.ebay.com, www.ebay.ca, www.ebay.co.uk, www.ebay.it.) Unfortunately, on eBay the images and the data are kept only for a limited time. That's the main reason why my site was set up. I don't know how long the links that are given below will be alive, but anyway, you can use them as a starting point. On this site I provide separate links to every given lens, so you can show exactly to anybody what kind of lens are you looking for, or plan to use for your project.
My lens image and data collection has more than a thousand photographs in more than 150 Mbytes - and is growing day after day.
