Abstract: An image-acquiring equipment with camera with linear sensor is described, having a telecentric optical objective whose main lens 23 is of the cylindrical type, placed in the same way as of the main lens of a known telecentric optics; the lens 23 can be of an a-cylindrical type, with profile computed for removing the cylindrical aberration; the optical assembly 13 for forming a real image 16 on the sensor 26 of the linear camera can be replaced with an optics of the photographic type, obtaining the best possible exploitation of the opening A of the main lens 23, greatly simplifying the construction of the telecentric optics; the image-acquiring equipment comprises a telecentric optics 27, a lamp 34 and a camera 24 of the linear or array type, and is pertaining to a viewing system for dimensional, geometric, or metrological checks.
