摘要:
An axially symmetrical molded glass lens has a central longitudinal axis, a lens surface, an annular intermediate area and a mounting flange area. The lens surface is axially symmetric around the central longitudinal axis and is curved. The annular intermediate area is curved and axially symmetric, is formed around the lens surface and has a radius of curvature having a continuously vary modulus that decreases as the radius of curvature approaches the annular intermediate area. The mounting flange area is formed around and connects smoothly to the annular intermediate area. The axially symmetrical molded glass lens has fine precision, a high production rate and a low cost.

A diamond substrate and a method for fabricating the same are provided, wherein a protection layer is formed on one surface of a diamond layer in the process of forming the diamond layer by chemical vapor deposition process, for reducing the deformation of the diamond layer. Thereby the deformation of diamond substrate falls within the range of permitted tolerance of deformation, so that the performance of the diamond substrate is enhanced.

A mold for glass has a base and a diamond protective film deposited on the base. Due to the quality of the diamond protective film, the base can be protected substantially with a high temperature in the process of manufacturing the glass to extend the lifespan of the mold.

A method for fabricating a diamond diaphragm is provided, wherein a non-homogeneous energy, generated by a hot wire, plasma, or flame, for activating and dissociating gas is provided to pass above a mold. Due to different distances between a curved surface of the mold and the non-homogeneous energy, different heating effects are produced on the surface of the mold. When the diamond material is coated and grows on the surface of the mold, the growth rate of the diamond material appears to be different by location, thus, the diamond diaphragm has a non-homogeneous vibration characteristic, and thereby having a response bandwidth wider than that of a diamond diaphragm with homogeneous vibration characteristic.

A diamond substrate and a method for fabricating the same are provided wherein a SiC layer is formed on a lower surface of a diamond layer for preventing the diamond layer from being deformed after the process of forming the diamond substrate, and then a semiconductor layer is formed on the diamond layer or directly formed on the surface of the SiC layer. Thereby, the lattice mismatch between the diamond film layer and the semiconductor layer is mitigated by the SiC layer, and the crystalline quality of the semiconductor layer is improved, the fabricating process of the diamond substrate is simplified, and the performance and stability are enhanced.
