eROSITA mirror module

The first core com­po­nent of the eROSI­TA space tele­scope con­sists of sev­en iden­ti­cal mir­ror mod­ules aligned in par­al­lel. Each has a di­am­e­ter of 36 cen­time­tres and con­sists of 54 nest­ed mir­ror shells whose sur­face is com­posed of a paraboloid and a hy­per­boloid (Wolter I op­tics). They col­lect high-en­er­gy pho­tons and fo­cus them on­to the X-ray cam­eras.      

The first core component of the eROSITA space telescope consists of seven identical mirror modules aligned in parallel. Each has a diameter of 36 centimetres and consists of 54 nested mirror shells whose surface is composed of a paraboloid and a hyperboloid (Wolter I optics). They collect high-energy photons and focus them onto the X-ray cameras.
