Endoscope optical system |
| abstract |
An object of the present invention is to prevent the attachment of body fluids and water droplets to the surface of an optical member such as a lens even when it is inserted into a body cavity, etc. To provide an endoscope optical system that does not deteriorate. Among the objective lens and illumination lens arranged at the distal end of the insertion portion of the endoscope, the lens closest to the object side, or the outer surface of the cover glass is free of fluorine-substituted alkyl group-containing organosilicon compound and silicon. A coating film is formed using a coating material containing perfluoropolyether as a main component. [Selection] Figure 1 |
