An optical source for guiding light to a target of a patient includes at least one light source configured to emit red light and infrared light. The at least one light source is embedded within a light-conducting sheet. A photodistributor is spaced from the at least one light source. The photodistributor includes a light-emitting surface and at least one light-receiving surface optically coupled to the light-conducting sheet. The photodistributor is configured to discharge at least a portion of the emitted red light and at least a portion of the emitted infrared light into a target.

According to one embodiment, a reflector device is disclosed. In one example, the reflector device comprises a reflector having a plus-shaped cross section, and at least one solid state light emitting element. The reflector may comprise at least a first and a second surface portions, which extend in planes intersecting at an angle, said at least one solid state light emitting element being mounted to one of said first surface portion or said second surface portion.

Reflector device and lighting device comprising such a reflector device

A reflector device comprising a reflector (), having an inner surface (), and at least one solid state light emitting element (). The inner surface of the reflector comprises first and second surface portions (), which are flat and which extend in planes intersecting at an angle. The at least one solid state light emitting element () is mounted at at least one of said first and second surface portions () such that a major part of the light emitted from said at least one solid state light emitting element () illuminates the other one of said first and second surface portions ().

A drum-shaped workpiece (37) is machined according to a method whereby the workpiece (37) is fastened to a rotatable holder (1) of a machine tool (3) by means of an adhesive (45), for example a mixture including rosin and beeswax, such that a centerline (51) of the workpiece (37) coincides substantially with an axis of rotation (19) of the holder (1). This adhesive (45) is exclusively provided between the holder (1) and support surfaces (47, 49) of the workpiece (37) directed substantially parallel to the centerline (51), the workpiece (37) being brought into connection with the holder (1) exclusively via the adhesive (45). It is achieved thereby that mechanical stresses in the workpiece (37) caused by the fastening of the workpiece (37) to the holder (1) are as small as possible. A dimensional accuracy which the workpiece (37) has after being machined by the machine tool (3) and before being removed from the holder (1) thus remains intact when the workpiece (37) is removed from the holder (1). A drum-shaped carrier (83) manufactured by the method is used as a carrier of a selenium layer (101) in an X-ray diagnosis apparatus (85). A further drum-shaped carrier (107) manufactured by the method is used as a carrier for a selenium layer (129) in a photocopier (109).
