Example Embodiment
[0034] Such as figure 1 As shown, an embodiment of the present invention provides a method for preparing an optical glass element with a light absorption layer, which specifically includes the following steps:
[0035] Step S1: Perform surface pretreatment on the optical glass to form nanometer or micrometer gas diffusion channels on the surface of the optical glass; this step does not specifically limit the surface pretreatment method, in principle, as long as the surface of the optical glass can be formed at nanometer level Or micron gas diffusion channels can be selected, and the surface pretreatment includes but is not limited to at least one of sandblasting, acid etching, ion exchange, and quenching. In the surface pretreatment of optical glass, one of these methods can be used, or a combination of multiple methods can be used.
[0036] The sand blasting refers to hitting the glass surface with sand particles ejected at a high speed by a spray gun to form a fine uneven surface...
Example Embodiment
[0059] Example 1
[0060] A method for preparing an optical glass element with a light absorption layer specifically includes the following steps:
[0061] (1) Process the K9 glass listed in Table 1 to the rough size;
[0062] (2) Sandblasting the surface of K9 glass: use 1000 mesh Al 2 O 3 Particles, sandblasting the glass surface for 60s under an air pressure of 0.6MPa;
[0063] (3) Put the sandblasted K9 glass into a reduction furnace for high-temperature hydrogen reduction, the reduction temperature is 610℃, the hydrogen pressure is 0.2MPa, and the reduction time is 5000min;
[0064] (4) Process the reduced blank to the finished size.
[0065] After testing, the light absorption efficiency of the light absorbing layer is about 99.8%.
