Abstract
The invention provides a device for optically inspecting high temperature glass containers (2), the device comprising a lighting system (7) having a light-emitting surface that is adapted to emit both: a “flash” first light flux during a flash duration of less than 1 ms and at a wavelength longer than 650 nm; and also a “bottle-scanning” second light flux having wavelengths shorter than 650 nm and for a duration of not less than 2 s, the lighting system (7) being controlled: to emit the flash light flux so that the camera can take images of each container while back-lit by said flash light flux; and to emit the “bottle-scanning” light flux that is perceived by a human eye as being continuous.
