KLYPVE is an orbital detector of ultra high energy cosmic rays to be deployed on the Russian Segment of the International Space Station. An important part of the detector, which determines its physical parameters (energy threshold, field of view) is the optical system. For the project, a two-component system composed of a large area mirror-concentrator and a correcting Fresnel lens was developed. Two options were considered: a “Baseline” and a “Multieye telescope system” (METS). The first one consists of a 3.4 m diameter mirror and a 1.7 m lens and has 14 field of view. The second one consists of three identical telescopes with 10 field of view (a mirror of 2.4 m diameter and a 1.2 m lens) and can operate in various modes. The production of a mold for the central segment of the METS mirror was done in SINP MSU. This mold will be used for a carbon-plastic mirror manufacture. It is an important step in the development of lightweight and space qualified optical systems with high performance parameters production technology. A detailed description of the developed optical systems, optimization studies and simulations are presented as well as results of the mold production and first steps in carbon plastic mirror manufacturing.
