At least one lateral light cone is constituted on the main mirror connects the lighting fiber.
The coherent fiber bundle is using multi beam optical fibers according to the battle array arrangement of coordinate contraposition principle face, each optical fibers conduct
Coordinate position of the battle array upper pixel in face at coherent fiber bundle both ends corresponds.
The utility model has the advantages that：
1, the utility model proposes a kind of separable fibrescope, the lens of objective lens and eyepiece group all use
Die casting mode makes, and in contrast to techniques such as traditional milling, grinding and polishing, cut edge, gluings, processing cost is greatly lowered, and
Main mirror and outer telescop become medical disposable material, and subsequent eyepiece body portion may be reused, can further reduce the cost, because
And can largely be used in outpatient service as disposable products, cross-infection can either be avoided, also can be that hospital and patient are very big
Ground saves money.
2, due to making lens using die casting mode, the face shape of lens can be designed as aspherical or freely bent
Face can greatly improve image quality compared with traditional glass spherical lens or self-focusing camera lens.
3, can there are multiple lateral light cone connection optical conductors or light source on main mirror, different spectrum are selected convenient for observer
Light source is illuminated, and is improved and is checked accuracy.
