ている。2. Description of the Related Art Conventionally, various types of surface treatments have been applied to the surface of engineering lenses and filter lenses (hereinafter referred to as "filter lenses" or "lenses" at the ends), and especially for news steel used outdoors. A filter lens of a camera or a video camera whose surface has been subjected to a water-repellent treatment is often used because it is necessary to easily remove not only adhesion of water droplets due to rainfall but also attachment of dirt at an imaging site.

題点を有していた。Further, since multi-coated lenses such as a Polarizing (polarized) lens and a Circuit-Polyzing (circularly polarized) lens are bonded products, it is not possible to coat the outermost layer with an MgF 2 film having a strong coating film. In addition, peeling occurs due to the necessity of reheating the coat, making production impossible. Therefore, the multi-coated lens can only provide a coat film using SiO 2 as the outermost layer, and the strength of the coat film is weak.
In the use of the filter, there is a problem that dirt such as fingerprints is hardly wiped off, and abrasion is easily generated at the time of wiping.
