The system includes a horn antenna optimized for the W-band, the optical instrument that comprises a collimator and collector subsystems and a set of thermal and microwave blocking filters. The completed design is described based on the Gaussian beam and ray tracing approximation. The accuracy of the Gaussian beam approximation is used to avoid losses by vignetting and to optimize f/0.9 collector optics at 92.5 GHz. The final opto-mechanical design is showed.}, organization = {This work was supported by Spanish Ministry of Science, Innovation and Universities under Grants PID2019-105552RB-C41, MADE (PID2019-105552RB-C44) and PID2019-110610RB-C22.
