| 发明名称 | Illumination arrangement for an image field delimitation frame of a mixed-image viewfinder camera | ||
| 摘要 | In an illumination arrangement (1) for an image field delimiting frame (2) of a mixed-image viewfinder camera having an observation beam path (9) and a viewfinder beam path (3), the illumination arrangement is arranged in the viewfinder beam path (3) in the direction of light upstream of the image field delimiting frame (2), the illumination is formed by an active light source (14, 14′) and the viewfinder beam path (3) is mechanically delimited (16, 22) within the illumination apparatus (1) with respect to the light source (14, 14′). | ||

| 主权项 | 1. An illumination arrangement for an image field delimiting frame of a mixed-image viewfinder camera comprising: an observation beam path; and a viewfinder beam path, wherein a) the illumination arrangement is arranged in the viewfinder beam path in a direction of light upstream of the image field delimiting frame, b) an illumination is formed by an active light source, and c) the viewfinder beam path is surrounded by an opaque tube thereby mechanically delimiting the viewfinder beam path within the illumination arrangement with respect to the light source such that no light from the illumination formed by the light source reaches the viewfinder beam path. | ||
