Does anyone know whom I could get in touch with to make a three element
contact triplet lens--about 3 inches diameter, common glasses, coated? Who
does this kind of one-off work economically? This will be a Roland Christen
"Tri-Space" corrector to turn my trusty old Jaegers 6 inch f/10 achromat
into an apochromat. I haven't done lenses yet--always planned to do this
project but I haven't found time in the last fifteen years. Maybe if I see
how expensive it is to buy I'll get the urge.
