preparation example Construction

[0056] The present invention also provides a method for preparing the fluorophosphate optical glass according to the present invention, which includes: weighing each component according to the proportion, mixing them uniformly, melting them, and then pouring or leaking them into a molding mold, or directly pressing them .

[0057] Specifically, they are weighed according to the specified ratio, mixed into batch materials, put into a platinum crucible for smelting, stirred and melted at a temperature of 850-1050° C., and the stirring time is controlled at 2-4 hours. After stirring evenly, pour it into a molding mold, and finally process it through annealing and cooling to obtain the optical glass or optical element of the present invention.

[0058] The present invention also provides an optical element comprising the fluorophosphate optical glass according to the present invention.

[0059] The present invention also provides an application of the fluorophosphate optical glas...

Abstract

The invention provides fluorophosphate optical glass, a preparation method and application thereof and an optical element. The fluorophosphate optical glass contains the following components in percentage by weight: 40%-50% (preferably 42%-50%) of Ba(PO3)2, 5%-15% (preferably 6%-14%) of Al(PO3)3, 5%-10% (preferably 5%-8%) of BaF2, 10%-20% (preferably 12%-19%) of AlF3, 9%-15% (preferably 10%-14%) of CaF2, 0-8% (preferably 1%-8%) of SrF2 and 0-8% (preferably 2%-8%) of MgF2. According to the fluorophosphate optical glass, stable metaphosphates Ba(PO3)2 and Al(PO3)3 are selected as the main components of the glass, so that the complex production flow for directly adopting P2O5 in fluorine-phosphorus glass is simplified, and meanwhile, the damage of platinum caused by contact between P2O5 and platinum in a smelting process can be avoided. Meanwhile, the fluorophosphate optical glass provided by the invention is applicable to industrial batch production.

Description

technical field [0001] The invention relates to a fluorophosphate optical glass, a preparation method thereof, an optical element and an application thereof, and belongs to the field of optical glass. Background technique [0002] Fluorophosphate optical glass is a new type of glass material with low refractive index and low dispersion. In the optical system, it can eliminate the special dispersion of the secondary spectrum, improve the resolution, improve the imaging quality of the optical system, and has low softening characteristics. , can be directly precision molded into aspherical lenses, which can better apochromatize, eliminate spherical aberration and aberration, and reduce system volume and weight. [0003] At present, fluorophosphate optical glass has been widely used in high-precision, high-resolution optical instrument combination lenses such as digital cameras, high-definition monitors, and astronomical telescopes, and has become a new type of optoelectronic ma...
