Lighthouse Optic

Optic at the Jetty Foreshores

The optic of the South Solitary Island Lighthouse will soon be on public display at the Jetty Precinct.

It was made by Chance Brothers in Smethwick, England and is the only complete First Order eight panel lense in Australia, and one of four supplied to Australia.

The glass used, Crown glass, was a combination of French sand, lime, carbonate of soda, nitrate of soda and arsenic. When first produced the glass would have been clear, but exposure to ultraviolet light in combination with the trace elements have caused it to yellow over the years. The photos show the lighthouse which has been automated since 1975. – Chance Brothers lighthouses
