A curing chamber (10) for curing a workpiece by exposure to electromagnetic radiation, comprises at least three sidewalls (12, 14, 16, 18, 72) surrounding and at least partially defining an interior volume adapted to contain a workpiece. The sidewalls are reflective to electromagnetic radiation of a predetermined wavelength and each sidewall has a pair of opposed edges (121, 122, 141, 142, 161, 162, 181, 182), so that the edges of one sidewall are each located adjacent one of the opposed edges of an adjacent sidewall. The region between adjacent edges of adjacent sidewalls defines a respective elongated corner region (20, 74) in which there is located a radiation-emitting device (22). The radiation-emitting device, which may be an array of LEDs or other sources of suitable radiation to cure the workpiece, is of an elongate shape and is disposed along a corner region to emit electromagnetic radiation of said predetermined wavelength from a plurality of points along the length of the device into said interior volume when activated. The resulting distribution in radiation intensity within the chamber promotes more even and efficient curing of a workpiece.
