Description

Technical Field

[0001] The utility model relates to the technical field of optical element detection, and more specifically to a surface detection device for an optical element. Background Art

[0002] Optical parts, also known as optical elements, are the basic building blocks of optical systems. Most optical parts, such as lenses, prisms, and mirrors, function to form images. Lenses are optical components made of transparent materials. Convex lenses are thicker in the middle and thinner at the edges, and come in three types: biconvex, plano-convex, and concave-convex. Concave lenses are thinner in the middle and thicker at the edges, and come in three types: biconcave, plano-concave, and convex-concave. Lenses play an important role in astronomy, military affairs, transportation, medicine, art, and other fields. After lens production, their surface shape needs to be inspected. Optical element surface shape inspection is the process of checking the surface smoothness, flatness, and presence of scratches and cracks.
