A Transition Edge Sensor (TES) composite bolometer for Fourier Transform (FT) spectroscopy was designed, built and characterized. The design is based on a super conducting thermistor with SQUID readout, SiN membrane technology and a thin film metal mesh absorber which is optimized for the spectral range from 0.1 THz to 3 THz. A noise equivalent power (NEP) of 3.8*10-13 W/Hz0.5 was achieved with a linear dynamic range of at least four orders of magnitude.
