Abstract:
An optical inspection system for capturing images of backlit test objects on a detector at two or more aperture settings includes a telecentric imaging system having a first setting associated with a first size aperture stop and a second setting associated with a second larger size aperture stop. An illumination system includes a substage illuminator incorporating (a) a first set of one or more light sources surrounded by a first barrier that defines a first size aperture stop of the illumination system and (b) a second set of one or more light sources located beyond the first barrier and surrounded by a second barrier that defines a second larger size aperture stop of the illumination system. The first size aperture stop of the illumination system images to the first size aperture stop of the telecentric imaging system at the first setting and the second larger size aperture stop of the illumination system images to the second larger size aperture stop of the telecentric imaging system at the second setting.
Abstract:
A device and a method are provided for measuring the moisture in die cast molds, the cavity of which is connected via an evacuation conduit to an evacuation device. The modular assembly of the device is connectable to the evacuation conduit and includes a sensor assembly to measure the moisture of gases evacuated from the mold cavity. The sensor assembly includes an emitter emitting electromagnetic radiation and a detector detecting electromagnetic radiation. On the basis of the measured values obtained during the evacuation action it can be determined whether the amount of a water/release agent mixture jetted into the mold cavity needs to be altered before the actual casting action.

Abstract:
A light guide member for an object detection apparatus is devised. The object detection apparatus includes a light source unit, and a detection unit for detecting an object adhered on a surface of a light translucent member based on change of light quantity of reflection light received from the light translucent member. The light guide member includes an incident face where the light exiting from the light source unit enters; a detection face where the exiting light exits to a rear face of the light translucent member and the reflection light reflected from the light translucent member enters; an exiting face where the reflection light exits to the detection unit; and a light guiding portion through which the exiting light and the reflection light proceed. The detection face has curvature corresponding to curvature of the light translucent member.
Abstract:
A fluorescence detector for detecting fluorescence emitted from at least one sample contained in at least one sample unit, the fluorescence detector including at least one irradiating module which irradiates an excitation light to the sample; a fluorescence selecting unit which selectively transmits fluorescence emitted from the sample; a light-receiving unit which detects the fluorescence; and a telecentric lens positioned between the fluorescence selecting unit and the light-receiving unit, wherein each of the at least one irradiating module comprises: at least one light source which emits a light; an excitation light selecting unit which converts the light emitted from the at least one light source into the excitation light; and a beamsplitter which controls the excitation light to travel to the sample, and transmits the fluorescence emitted from the sample.
Abstract:
An illumination mean for the inspection of flat substrates is disclosed. The flat substrate includes an upper edge area, a lower edge area and a front area. The illumination means is formed as an annular segment and comprises an opening into which at least the edge area of the flat substrate extends. A plurality of light sources are arranged on an annular segment in a housing. Inside the housing, a reflective element is provided so that the light from the light sources does not impinge perpendicularly on the upper edge area, the lower edge area and the front area of the flat substrate.
