Abstract
In the last years the interest in high throughput focusing x-ray optics has been increasing rather rapidly. High photon collecting power is the most important requirement in scientific investigations that require for example measurement of line emission and temporal behavior of sources. Generally this type of observations need 10 time or more photons than source detection and position. Because of the operation at grazing incidence an high throughput x-ray telescope requires to be composed of a large number of nested confocal mirrors. To reduce the losses imposed by the obstruction of the mirrors wall and to keep the weight of the optical system within acceptables values, the thickness of the mirrors must be very thin. Nevertheless the angular resolution of the optics must be of a good standard (better than 1 min. of arc) in order to avoid sources confusion. The techniques of replicating the mirror shells from masters are capable to produce x-ray optics in accordance with the above mentioned requirements. The method of epoxy replication will be briefly reviewed in the paper while the technique of replica by electroforming will be discussed in more details, underlining the possibility of using more elaborated electroforming processes for the manufacture of light weight large aperture x-ray optics.
