in the figure, what does S’s – for the sagittal plane means? the distance between the image point and the sagittal plane ??
I see in some papers,they use toroidal mirror to collimate the beam from a point source, how does this happen and why? some material say toroidal mirror have two focus point, where is it?
any thing help would be appreciated
best wishes!
