The photo to the left was taken after the first-order revolving lens was disassembled, repaired, and reassembled
in 2001 (see photos of the reassembly below). Note the temporary light attached to the balcony -- the modern day equivalent
of the classical Fresnel lens.
The original lens was removed after it was found to be approximately 6 inches out of plumb -- all the weight had shifted
to one side. How would this have affected its operation?
A person who repairs lenses and their mechanical systems is called a lampist. Why do you suppose they
were given that name?
