In a radiation treatment apparatus comprising a reflector (1) and a lamp (2), there is arranged a combination of infrared filters allowing a spectral range comprised between 800 and 1200 nm. The combination of filters is comprised of two filters (3, 4) arranged one behind the other. One of the filters (3) has a transmission maximum for wavelengths comprised between 900 and 1100nm and the other one (4) of wave-lengths comprised between 700 and 900nm. Each filter has a reduced transparency in the maximum transmission area of the other filter. |
