What is the formula that relates surface (m^2) of a circular convex lense with temperature (Celsius) in a light focus point of a lense.
(calculating temperature in the light focus according to size of a lense...)
(Glass lense, regular... (so, no coefficients, just assume it's some nice common average colourless glass lense... Some simple forumula, something practical - you get what I mean...))
(I guess it relates [power of sunlight]per[unit of surface]...)
Example, please...
---------
(...and formula for mirror used instead of lense to concentrate light (I guess it's a better solution, but nevertheless I prefere lense))
Link if there is a place you know where I could find it (it's a too complex concept, google gives me all sorts of irrelevant results)
---------
Thank you in advance.
