Abstract
The invention provides a high-temperature-resistant optical lens, which includes a shell. A light channel is arranged in the shell. The light channel is sequentially provided with a first negative focal lens, a second negative focal lens, a third negative focal lens, a fourth positive focal lens and a fifth positive focal lens from front to back, the first negative focal lens is a convex-concave lens, the second negative focal lens is a plano-concave lens, the third negative focal lens is a plano-concave lens, the fourth positive focal lens is a biconvex lens, and the fifth positive focal lensis a plano-convex lens. The first negative focal lens, the second negative focal lens, the third negative focal lens, the fourth positive focal lens and the fifth positive focal lens are arranged inthe shell, observation in a high-temperature environment is achieved, direct contact between a human body and equipment and the high temperature is avoided, the service life of the equipment is prolonged, and harm of the high temperature to the human body is avoided.
Description
technical field [0001] One or more embodiments of this specification relate to the technical field of high temperature resistant optical lens, in particular to a high temperature resistant optical lens. Background technique [0002] With the application of lenses more and more widely, people's demand for cameras is not limited to ordinary shooting effects. The applicant finds that the existing lens has the following problems during use: the lens cannot be used in a high temperature environment. Contents of the invention [0003] In view of this, the purpose of one or more embodiments of this specification is to propose a high temperature resistant optical lens to solve the problem that the lens cannot be used in a high temperature environment. [0004] Based on the above purpose, one or more embodiments of this specification provide a high-temperature-resistant optical lens, including a housing, and a light channel is arranged in the housing, and the light channel is sequ...
