Abstract

The invention discloses a cleaning technology for an infrared chalcogenide glass lens. The cleaning technology comprises the following steps that 1, the infrared chalcogenide glass lens to be cleanedis pretreated; 2, the pretreated lens is placed into a first cleaning groove and soaked with pure water; 3, the lens soaked with pure water is placed into a second cleaning groove and ultrasonically cleaned through non-ionic surfactant cleaning agent; 4, the lens cleaned in the step 3 is placed into a third cleaning groove, a fourth cleaning groove and a fifth cleaning groove in sequence, and ultrasonically cleaned through pure water; and 5, the lens cleaned in the step 4 is dried through centrifugal dripping. The cleaning technology for the infrared chalcogenide glass lens is better in cleaning effect and more environmentally friendly compared with the prior art.

Description

technical field [0001] The invention relates to a cleaning process for infrared chalcogenide glass lenses. Background technique [0002] Infrared chalcogenide glass is widely used in the infrared thermal imaging camera industry. The infrared thermal imaging camera industry is an emerging high-tech industry with very broad development prospects. It is also the largest market share in infrared application products, and it has a wide range of applications in both military and civilian fields. Infrared thermal imaging cameras have been widely used in military weapons such as satellites, missiles, and aircraft under modern warfare conditions. At the same time, as the production cost of uncooled infrared thermal imaging technology has been greatly reduced, the application of this product has been extended to various sectors of the national economy such as electric power, fire protection, industry, medical treatment, and security. Because infrared chalcogenide glass materials are...
