FEATURE LIGHTHOUSE - This months Feature Photo is Split Point Lighthouse, photographed by Marinegirl
Split Point Lighthouse is a lighthouse located in Aireys Inlet—a small town on the Great Ocean Road, Victoria, Australia.
History
Originally called Eagles Nest Point, the lighthouse was originally built in 1891. It was converted to automatic operation in 1919.
The original British-made lens is still in use. However, the factory in Birmingham, where the lens was built, was bombed during war-time and the essential formulas for making the unique lens crystal were lost, should a replacement ever be needed.
A Japanese firm, consulted by the Australian Maritime Safety Authority, estimated the cost of replacing the lens at more than AUS$1 million.
Under standard Australian lighthouse convention, red filters would usually be placed to the extreme left and right of the beam (indicating "danger zones" for a passing ship, in-line with the jagged coastline). For reasons unknown, the Split Point Lighthouse operated for many years under the opposite system; although this has now been corrected.
The original lighthouse keeper's quarters, a detached house adjacent to the site, is now a privately owned residence.
Today
The view from the top of the lighthouse.Since summer 2005, the Split Point Lighthouse has been offering regular 30 minute guided tours, during which visitors have the chance to climb the original staircase and experience the view from the balcony just below the latern room. Tours had been available for much of the 1990s, but on only a few days per year.
The top of the lighthouse is also now used as a mobile phone base station, making it dangerous to enter the lantern room (or any area above) whilst it is in operation, due to possible exposure to RF radiation.

Lighthouse Trek
As the exploration of our world expanded in its infancy, which resulted in colonies springing up around the globe, the lighthouse became a beacon of hope for safe travel along our ocean's coast as well as a navigational guide for the sailors on the vast Seas that lap the shores of the globe.
Now as technology can thrust humanity across the globe in a fraction of the time it once took and with the introduction of GPS, lighthouses are fading into this worlds history.
The Lighthouse Trek Group is set up to capture on photo and share with others who love lighthouses this part of our world’s history, and in so doing showing by photography the importance of preserving this part of history in hopes that some person or organization will step up to help restore the ignored and dilapidating lighthouses.
Hi my name is Mark, a member of the United States Lighthouse Society. I am the founder of the Lighthouse Trek Group, with me is my wonderful twin sister Sharon who is the other Lighthouse Keeper in Lighthouse Trek and with us is a very good flickr friend of ours Gary a moderator for our group and we would like to welcome you to the Lighthouse Trek Group.
Please feel free to add your lighthouse pictures as we are all on our Lighthouse Trek. However, for each picture that you post, please comment on at lease two photos using our html snippet that you saw the photo in Lighthouse Trek as shown below between the dashes:

A brief history of the Fresnel lens in historic lightouses.
Augustin Jean Fresnel (1788 - 1827)
Fresnel (pronounced: Fur-nel)
An accomplished engineer and scientist, Fresnel changed our understanding of how light behaves and can be manipulated and intensified. His revolutionary system of lens optics replaced the system of multiple parabolic reflector and lamp assemblies with a single lamp inside of a single lens. Fresnel lenses are used today in traffic signals, infrared motion detectors, theatre projection systems, photographic equipment, industrial optics, environmental monitoring equipment, astronomical equipment and automobile lights.
The basic idea behind a Fresnel lens is simple. Imagine taking a plastic magnifying glass lens and slicing it into a hundred concentric rings (like the rings of a tree). Each ring is slightly thinner than the next and focuses the light toward the center. Now take each ring, modify it so that it's flat on one side, and make it the same thickness as the others. To retain the rings' ability to focus the light toward the center, the angle of each ring's angled face will be different. Now if you stack all the rings back together, you have a Fresnel lens. You can make the lens extremely large if you like. Below is a cut out section of a Fresnel Lens to give you an example.
To bend and focus the rays to form a single, concentrated beam of high intensity light, the catadioptric prisms refract and reflect; the dioptric prisms and center bull's eye lens refract. With just a 1000 watt bulb, a first-order Fresnel lens can generate a 680,000 candlepower beam visible up to 21 miles out to sea if set high enough.
The sizes of the Fresnel Lneses used in Lighthouses are catagorized by the order of the lens, the largest of which is a "First Order lens". When you are looking at lighthouses they will often tell you what order lens is in that spisific Lighthouse such as it has a First Order Lens, or a Third Order Lens etc. below is a chart to give a rough idea of how big the lens is according to the order of the lighthouse lens.
