Lobster-eye optics have attracted much attention and effort in recent years due to their unique x-ray focusing capabilities. While many advances have been made in the manufacture and analysis of these optics, their characterisation and the determination of their metrology remains constrained by the shortcomings of current techniques.We present a faster, better and cheaper method for the determination of many of the metrological parameters of lobster-eye optics. Optical images of the entrance and exit surfaces of an optic are taken. Applying our technique to these images allows measurement of all the geometrical properties that previously have been found to be the major contributors to focusing defects. In addition, the number of free parameters required in fitting a simulated to a measured x-ray image can be greatly reduced. We present results for the characterisation of an existing lobster-eye optic and the improved modeling thereby obtained which are in very good agreement with experimental x-ray focusing data.

“…5 Although, it is worth noting that their potential as neutron lenses has only more recently been demonstrated. 6 The effort in recent years has been towards developing fabrication and analysis techniques in order that actual lobster-eye optics approach their potential.…”

“…However, only recently, there were overcome principal difficulties in manufacturing the LE-X-ray telescope mirror optics with required tolerance. The construction of the mirror has been based on technology of bent MCP [59][60][61] or on an electro-chemical etching of silicon [62]. Recently, a wide-field lobster-eye X-ray telescope project has been proposed to study the astronomical X-ray sources during the planned satellite mission [63].…”
