Abstract
An optical web monitoring apparatus has an illuminating arrangement which images the pupil of the source of illumination into the observing pupil of the camera objective (18) of a diode row camera using a strip-like concave mirror (14), or two strip-like concave mirrors (14, 15), and thus achieves the maximum attainable light yield. The construction is realized such that a fault seeking apparatus with a laser scanner can be used at the same time using the same mirror strips (14, 15). Thus two monitoring operations can be carried out simultaneously.
