ABSTRACT:
An apparatus for concentrating light from a linear field on to a relatively small receiver disposed at the end of a rod light guide on the peripheral surface of which light emanating from the linear field is directed. The linear field is arranged substantially at the focal distance from a first concave strip mirror which is disposed so as to extend optically parallel to the field and reflects the incident light from the field to a second concave strip mirror which is optically parallel with the first mirror and forms therewith a substantially telecentric system and which, in turn, reflects the incident light to the peripheral surface of the rod light guide.
