I need advice of local optical theory gurus.
I need to find out parameters for a paraboloid reflector to reflect all light radiated by a T5 fluorescent tube. T5 means the tube is 5/8" in diameter.
My current polished aluminium reflector for an aquarium tank has a primitive \_/ shape with only two bends

and in fact is worse looking from the transport than the one in the picture, it resembles more |_| causing most of the light from the back of the tube to get lost ("re-strike" phenomenon).
This gave me an idea that when I will try to reshape it, I may better give it a paraboloid shape.
So the optical problem is like this - if you have a spherical focal plane of 5/8" what size and shape needs the reflector to be ?
As you can see in the photo, the tubes are rather crammed together so there is not much space for the diverging sides of the reflector..
