Condenser lens



Keith Wilson asks about a replacement condenser lens for his projector.
 I had a similar need to replace one in my Stereomatic 500 a
couple of years ago. (My friendly repair man had broken it while
replacing the two mirrors!!)

I looked up specialist optical suppliers in my yellow pages
and found a small company that prepares lenses for opticians.
I called in with one of the good lenses , they put it on a special
machine which measured its optical properties , checked the
size and then ordered me one from their suppliers. This they then
ground down to the correct diameter. In 48 hrs I had a new matching
replacement , which has given good service ever since.
I used PD Optics of Sheffield , but I think most big towns would have
a similar outfit.

Just realised my previous posting on Coronet violated the 40 col
format- sorry everyone!

Best wishes,
John Bradley
