Description

Endoscope optical performance detection device Technical Field The utility model relates to the technical field of endoscopes, in particular to an endoscope optical performance detection device. Background In the current endoscope technology field, endoscope optical performance detection faces a number of challenges. The conventional endoscope optical performance detection device has obvious defects when the endoscope is fixed. On the one hand, it is difficult to achieve efficient and stable fixation of both front and rear ends of an eyepiece of an endoscope. In the detection process, the endoscope is easy to move forwards and backwards, which not only affects the detection accuracy, but also can cause deviation of the detection result, and whether the optical performance of the endoscope is qualified can not be accurately judged. For example, when some precision endoscopes are detected, the slight forward and backward displacement of the precision endoscopes may cause blurring, deformation, etc. of the observed pictures on the display screen, which interfere with the judgment of the optical performance. On the other hand, even if preliminary fixation is achieved, the endoscope still has a problem of shaking. This makes it difficult to ensure stable observation and imaging effects during detection. Whether manual observation or photographing through a digital camera is carried out to observe pictures on a display screen, the shaking can lead to inaccurate observation results, and whether the optical performance of the endoscope meets the use requirement cannot be clearly judged. Moreover, the traditional fixing mode is often complicated, the operation is inconvenient, a great deal of time and energy are consumed, the detection efficiency is reduced, and the actual requirements for rapidly and accurately detecting the optical performance of the endoscope cannot be met.
