We present a passive, fully-staring THz imaging system for security screening purposes. The camera is equipped with a multi-kilo-pixel detector array of kinetic inductance bolometers, cryogenics operating above 5 K, and a multiplexed low-noise electronics to readout the whole detector array. After briefly describing the system, we concentrate on the optical system of the instrument. We discuss the trade-offs related to the optics and justify the adopted lens material and design. Furthermore, we show measurement results characterizing the related optical performance.
