I can HIGHLY recommend the HIROX system sold in the US by CALTEX in Fremont, CA 
(Phone 510-770-8808).  They have with variable mag lenses in the 20X-100X and 
50X-300X ranges with VERY sharp image and a machine driven head w/prism giving a
45degree view of the joints (has to be seen to be appreciated.)  

The standard lenses don't have a 6" focal length but they have made lenses like 
that (and may have an "off the shelf" version now.)

Hello,

We are looking for information on vendors and/or products 
offering CCTV/Camera systems with the following criteria:

 A focal length of approximately 6"
 A magnification of approximately 100X

Picture clarity, sharpness, resolution, and color are extremely 
important.  This application is for optical die inspection.
