Optical glass molding technology is widely used
Optical glass lens molding technology is a high-precision optical component processing technology. It puts the softened optical glass into a high-precision mold and directly molds it under temperature, pressure and oxygen-free conditions. Use the required optical parts. This technology has become one of the most advanced optical component manufacturing methods in the world. Since this technology can directly press and form precision aspherical optical glass parts, it has created an optical instrument that can widely use aspherical glass optical parts. era. Therefore, it also brings new changes and developments to the optical system design of optoelectronic instruments, which not only reduces the size of optical instruments, reduces the weight, saves materials, reduces the workload of optical parts coating and workpiece assembly, and reduces the cost. It also improves the performance of optical instruments and improves the quality of optical imaging.
Do you know how widely the application of optical glass molding technology is applied? Let’s take a look at it:
At present, optical glass lens molding technology has been used to mass produce precision spherical and aspherical lenses. In general, in addition to the general production of lenses having a diameter of about 15 mm, it is also possible to produce large-diameter lenses, microlens arrays, and the like having a diameter of 50 mm. It is now possible to manufacture a microlens array of 100 μm in diameter per lens.
(1) Manufacture of spherical and aspheric optical glass parts used in military and civil optical instruments, such as lenses, prisms, and filters;
(2) manufacturing an aspherical lens for a fiber coupler for optical communication;
(3) A concentrating aspherical lens for manufacturing an optical disk. An aspherical optical glass lens manufactured by a compression molding method can replace the three spherical lenses used in the optical lens of the optical disc reader. Due to the high precision of the molded aspherical lens, it is possible to control and correct the axial aberration of the large numerical aperture, and also reduce the weight and cost of the original optical lens by 30 to 50%.
(4) Manufacturing an aspherical optical glass lens of a camera viewfinder, an aspherical lens of a film projector and a camera lens, and the like.
