Embodiment 1

[0019] Such as figure 1 As shown, an optical structure for an oral scanning mirror includes an optical structure, and the optical structure includes a biconvex lens A1, a diaphragm 2, a meniscus negative lens 3, a plano-concave lens 4 and biconvex lens B5;

[0020] The biconvex lens A1 and the diaphragm 2 are set close to each other, the air gap between the biconvex lens A1 and the meniscus negative lens 3 is 1.10-1.14mm, the air gap between the meniscus negative lens 3 and the plano-concave lens 4 is 4.75-4.79mm, and the plano-concave lens 4 The air gap with the biconvex lens B5 is 4.56-4.60mm, and the rear side of the biconvex lens B5 is provided with a glass sheet 6, and the rear side of the glass sheet 6 is the image surface 7, which simplifies the optical structure and simplifies the process of light transmission , which not only effectively reduces the interference of external factors, but also effectively reduces the distortion, making the image transmitted by the lens...

Embodiment 2

[0040] As another object of the present invention, provide oral cavity scanning mirror, this oral cavity scanning mirror especially the optical structure in embodiment 1, be provided with above any optical structure in oral cavity scanning mirror, therefore, oral cavity scanning mirror can obtain the above Any beneficial effect of the described optical structure will not be repeated here.

Abstract

The invention discloses an optical structure for an oral cavity scanning mirror and the oral cavity scanning mirror. The optical structure comprises an optical structure body and is characterized in that the optical structure body comprises a biconvex lens A, a diaphragm, a meniscus negative lens, a plano-concave lens and a biconvex lens B which are sequentially arranged from left to right along a light incidence direction. Through the biconvex lens A, the diaphragm, the meniscus negative lens, the plano-concave lens and the biconvex lens B which are sequentially arranged from left to right, the optical structure is simplified; meanwhile, the light transmission path is simplified; interference of external factors is effectively reduced; distortion is also effectively reduced, so that images transmitted by the lens equipped with the optical structure are more real; and prevention and later treatment of oral diseases are facilitated.

Description

technical field [0001] The invention belongs to the technical field of oral cavity scanning, and in particular relates to an optical structure for an oral cavity scanning mirror and the oral cavity scanning mirror. Background technique [0002] Oral health is an important part of general health. In 2007, the World Health Organization pointed out that oral disease is a serious public health problem that requires active prevention and control. Oral diseases such as caries, periodontal disease, etc. will destroy the hard tissue of the teeth and the supporting tissues around the teeth. In addition to affecting the functions of chewing, speech, and aesthetics, they will also cause difficulties in social communication and psychological disorders. Some microorganisms exist in the oral cavity for a long time, which can cause or aggravate certain systemic diseases such as coronary heart disease, diabetes, etc., endanger the health of the whole body and affect the quality of life. Th...
