Problems solved by technology

However, in order for the optical glass material to obtain optical properties equivalent to those of the original glass material after glass molding, the composition of the optical glass material must be re-adjusted. Therefore, the disadvantage of this Japanese patent is that the composition of the optical glass material is adjusted. The problems to be considered are more complicated, which also increases the complexity of the production method

Embodiment 1

[0028] A specific embodiment one of the manufacturing method of the optical glass assembly of the present invention is to refer to figure 2 and briefly explained below.

[0029] First, step S21 is carried out, and the forming temperature of about 610° C. 1 value and vd 1 The lanthanum (La)-based glass preforms with values ​​of 1.6935 and 53.2 were shaped and cooled to 520°C with a cooling time of 120 seconds after shaping to obtain a nd 2 value and vd 2 The values ​​are about 1.69±50×10 -5 And 52.75 ± 0.4 of the glass forming body and complete the glass molding process. In this specific embodiment one, the nd 2 value and vd 2 Values ​​are compared to the nd 1 value and vd 1 The value is reduced by about 3.5×10 -3 and 0.45.

[0030] Further, carry out step S22, under the condition that this glass forming body does not need to implement annealing process, can directly according to the optical characteristic of this glass preform after glass molding (that is, the nd 2...

specific Embodiment 2

[0033]A specific embodiment 2 of the manufacturing method of the optical glass assembly of the present invention is substantially the same as the specific embodiment 1, and its difference only lies in the nd of the glass preform of the specific embodiment 2 1 value and vd 1 The values ​​are 1.68893 and 31.1 respectively; the forming temperature of the glass molding process in this specific example 2 is about 570°C, and the cooling condition after shaping is to drop the temperature from 570°C to 480°C in 90 seconds. obtained nd 2 value and vd 2 The values ​​are about 1.68319±50×10 -5 And 31.6±0.25; In this specific embodiment two, the nd 2 value and vd 2 Values ​​are compared to the nd 1 value and vd 1 The value is reduced by about 5.7×10 -3 and 0.5.

[0034] To sum up, the manufacturing method of the optical glass component of the present invention can reduce the production cost and time cost of the optical glass component, further improve the production efficiency of ...

Abstract

The invention relates to a manufacturing method of an optical glass subassembly, which comprises the following steps that: (a) the optical characteristic of the glass module formed by a glass is used as a design norm to decide the design condition of the optical glass subassembly, and the glass prior formed body is exerted to the glass module manufacturing process to form a glass forming body; (b) according to the design condition of the optical glass subassembly, a post processing is exerted to the glass forming body to obtain the optical glass subassembly.

Description

technical field [0001] The present invention relates to a method for manufacturing glass components, in particular to a method for manufacturing optical glass elements (glassoptical elements). Background technique [0002] refer to figure 1 , the following briefly describes a conventional manufacturing method of optical glass components. [0003] First, step S11 is carried out, and the refractive index (refractive index, nd value for short) and dispersion of a glass preform before a glass molding (molding), generally represented by Abbe number (Abbe-number), referred to as vd value] is a design basis and determines the design conditions of an optical glass component. [0004] Further, proceed to step S12, subjecting the glass preform to a glass molding process to form a glass forming body. [0005] Next, step S13 is performed, applying an annealing process to the glass forming body so that the optical properties of the glass forming body recover to the refraction value an...
