Over the past thirty years, endoscope technology for imaging has been developing and expanding its field of application. This technology is best known and used in the medical field for diagnosis and surgery. The flexible endoscope, made up of optical fibers , helps reach parts of the anatomy where access is sinuous (esophagus, stomach, colon, etc.). The rigid endoscope, in which the stem is equipped with lenses, allows for the exploration of an area in a rectilinear field and facilitates the detection and surgical treatment of tumors, infections, or malformations by minimizing the invasive nature of the intervention. <\/p>\n\n\n\n
Multiple innovations have largely contributed to the improvement of the endoscope. The camera associated with the endoscope has, in particular, seen numerous developments. A true product of technology, it has benefited from improvements made to mobile phone cameras in terms of size and image quality. More compact, with better image definition and fields of view of up to 170\u00b0, endoscopic cameras are particularly appreciated by surgeons. They provide access to additional areas of the patient’s body with less trauma and faster recovery times.<\/p>\n\n\n\n
In order to offer patients and the medical profession less invasive and more efficient solutions, manufacturers of medical equipment face real challenges. They must not only find innovative solutions in miniaturization and improvement of image quality but also ensure that these solutions are reliable and manufacturable . <\/p>\n\n\n\n
It is in this context that PIS\u00c9O , a center of innovation and expertise specializing in the integration of optical-photonic technologies, was entrusted with a project to develop an optical system for rigid endoscopes. This included the study of a set of very small lenses adapted to the characteristics of a new sensor and the specific needs of one of its customers while taking into account integration and manufacturability constraints.<\/p>\n\n\n\n
