I am working on a hypothetical Solar scope design were i intend to put a Baader D-ERF behind the telescope optics, and i was wondering if the 75mm D-ERF can withstand about 50 Watts of solar light.
When i calculate how much power the filter has to withstand when its infront of the Lens i end up with about 25W.
I calculated this value as fallows:
P_ERF = P_SUN * (Pi * R²)
were i used 1.366KW/m² as the value of solar energy per m²
All values were calculated in m²
If i am wrong with this calculation, please correct me.
If the filter can not withstand the power, then i will need to rethink the Telescope design.
Also could a Etalon be theoretically used with a Hershel wedge type energy rejection system. In this setup i would reflect the excesses solar radiation away from the etalon, and leave it with enough light to operate the camera.
