Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] The production process method of the infrared cut-off filter of the present invention comprises the following steps: 1) glass sheet coating;

[0023] 2) glue the multi-layer glass sheets together;

[0024] 3) Cutting the multilayer glass sheets glued together;

[0025] 4) rounding the multi-layer glass sheets;

[0026] 5) Foamed glass sheets after coating;

[0027] 6) Cleaning of glass sheets after coating;

[0028] 7) The glass sheet after coating is dried;

[0029] 8) Put the cut lenses into the injection molding board for packaging,

[0030] In the step 2), yellow wax is used for gluing between the glass sheets. It has been verified by experiments that the gluing effect of yellow wax with a concentration of 8:1 is the best. Heat the yellow wax to 118°C-120°C, put the jig into the yellow wax, manually move the glass vertically in the yellow wax, after a ...

Abstract

The invention discloses a production process method of infrared cut-off filters, which is characterized by comprising the following steps of: (1) coating glass sheets; (2) drying the coated glass sheets; (3) sticking multiple layers of glass sheets together; (4) cutting the multiple layers of glass sheets stuck together; (5) rounding the multiple layers of glass sheets; (6) soaking the coated glass sheets in glue; (7) cleaning the coated glass sheets; and (8) packaging cut lenses on injection molding plate. In the production process method of the infrared cut-off filters, multiple layers of the coated glass sheets are stuck together by using yellow wax and other adhesives, so that lenses have good locating effect in the cutting process, multiple lenses can be cut at one time, and the automatic production of the lenses becomes possible.

Description

technical field [0001] The invention relates to a production process method of an infrared cut-off filter, belonging to the technical field of optical product production. Background technique [0002] Infrared filters are widely used in military, digital imaging, optical holography and photoelectric technology, so they have broad market prospects, especially infrared cut filters, which have become an indispensable part of digital products. Their performance It directly affects the quality of digital imaging. In order to realize the production of infrared cut filters with a high yield rate, excellent film system design and production process methods are required. Like the production process of other parts, optical parts must be tested for product quality after coating. Since the performance of optical films is plated according to the design requirements of optical instruments, it has specific optical requirements, usually for infrared cut filters. The quality inspection item...
