It will be interesting to see how the Fresnel lens concept works at sub optical wavelenghts and how they are effected by angle of incidence, in any case it looks a more cost effective way to build sensor micro lenses. -- Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://picasaweb.google.com/distudio/PESO http://home.swiftdsl.com.au/~distudio//publications/ Pentax user since 1986, PDMLer since 1998 -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
