OP Thanks, Bean. I'd like to try a larger lens with a wider field. It is tiring having to hold and move this lens. It is part of a light such as draftsmen use, It at one end of an arm with three pivoting joints, with counterbalancing springs. Originally the lens was surrounded by an 8 inch circular fluorescent, which is too bright to use. Edmund Scientific apparently doesn't have the big lenses they used to. Of course, a Fresnel lens doesn't give a sharp enough image.
