Abstract
An illumination system for inspection of devices is disclosed. The system includes a frame for positioning over an image area. A plurality of light source groups are coupled with the frame and are each configured to produce one or more wavelengths of light. Each light source group is configured to produce a wavelength of light which is not produced by another light source group.
Claims51
An illumination system for inspection of devices, comprising:
- a partially cylindrical dome frame for positioning over an image area;
- and
- a plurality of light source groups coupled with the frame, each light source group configured to produce a wavelength of light which is not produced by another light source group, wherein each light source group has a distinct range of incident angles.
A method for inspecting a device, comprising:
- positioning a partially cylindrical dome frame over an image area, the frame including a plurality of light source groups, each light source group is configured to produce a wavelength of light which is not produced by another light source group, wherein each light source group has a distinct range of incident angles;
- and
- generating a plurality of images, each image generated from the light produced by a different light source group.
A method of illuminating a device to be inspected, comprising:
- positioning a partially cylindrical dome frame over an image area;
- and
- illuminating the image area from a plurality of light source groups attached to the frame, each light source group being configured to produce a wavelength of light which is not produced by another light source group, and wherein each light source group has a distinct range of incident angles.
An illumination system for the inspection of devices comprising:
- a partially cylindrical dome frame for positioning over an image area;
- a first light source group comprising light sources operable to produce a first wavelength of light;
- and
- a second light source group comprising light sources operable to produce a second wavelength of light;
- and
- wherein each light source group has a distinct range of illumination angles.
An illumination system for inspection of devices, comprising:
- a partially cylindrical dome frame, having a geometry defined by a radius beginning at an image axis on an image plane so as to form a partial cylinder about the image axis, for positioning over an image area;
- and
- a plurality of light source groups coupled with the frame and configured to produce one or more wavelengths of light, each light source group configured to produce a wavelength of light which is not produced by another light source group.
