We present the design and the present development status of a 204 pixels mm-wave bolometric camera compatible with
the 30 meter IRAM telescope at Pico Veleta. Sequential and non-sequential ray-tracing and physical optics simulations
have been performed with ZEMAX, taking into account the IRAM mirrors and the telecentric camera. The focal plane is
made by an array of antenna-coupled NbSi microbolometers, described in brief. We present the cryostat design, and then
more in details the optics and the baffling system. We conclude with a brief discussion on the future perspectives toward
the multi-thousands pixels bolometric mm-wave camera at IRAM.
