Inventor: FUJII AKITO
IPC: C03B11/00
Filed: 2009-06-30
Abstract: PROBLEM TO BE SOLVED: To obtain a ceramic lens which exhibits excellent optical characteristics while suppressing increase of its production cost.SOLUTION: The ceramic lens 1 is formed by molding, wherein a PV value of a lens surface is equal to or less than a standard PV value (in μm) represented by formula of (sag)/(lens effective diameter×100)+1, when a level difference between the center of the lens surface and the outer edge of the lens effective diameter (in μm) in a direction along the lens optical axis is represented by sag (in μm), and the residual stress of the lens surface is 5 MPa or less. As a result, a surface shape of the ceramic lens 1 has sufficient accuracy, and consequently lowering of optical characteristics based on deterioration of the surface shape (e.g. deviation of the focus of the lens, lowering of resolution thereof, etc.) is prevented. Furthermore, as the residual stress of the surface is 5 MPa or less, variation of a refractive index of the ceramic lens 1 due to the residual stress is suppressed to a level having no problem in practical use.
