Note that in this reference Cg is defined using a circular active area instead of square, so the geometrical concentration 385x in it corresponds to 302x here.

14. The same BK7 glass has been considered for all the SOE’s under comparison. Though BK7 can be molded (see for instance, 8Hhttp://www.rpoptics.com/index.php?page=rpo-moldable-glass-data) is more common the use of, for instance, B270. The light absorption in B270 is slightly higher than in BK7, which causes that if the comparison is done using B270, the efficient of the RTP (whose optical path is longer) is penalized the most 9H.

The design with highest CAP* in this reference has a rotationally-symmetric CPC-type TIR-based secondary. It achieved CAP* = 0.54 for a square aperture and square cell (for which the FK has a higher value of CAP* = 0.57-0.61). Moreover, it produces a poor irradiance uniformity. It also has the encapsulation problems discussed in Section 5.
