Investigating the use of magnesium fluoride in infrared lenses In general, magnesium fluoride is widely used in the optics and laser industry, and one of its main uses is the production of camera lenses, especially infrared lenses. One of the most important raw materials for the production of infrared lenses and night vision cameras is magnesium fluoride nano powder, which, of course, only some countries have the technology to produce it. In Iran, the production of magnesium fluoride nano powder started in 2018 and before that this chemical compound was imported from China. The import of magnesium fluoride nano powder used to withdraw a large amount of foreign currency, but now its production in the country is being carried out on a large scale by different countries. Magnesium fluoride nano powder is produced in Iran with a high purity of 99.9% and is of very high quality. In addition, some domestic producers are exporting this chemical composition to various countries in the Middle East. The following are the most important features of magnesium fluoride nano powder used in the production of infrared lenses: It has a melting temperature above 1200 degrees Celsius Having the ability to dissolve in water Having anti-reflective properties It has excellent mechanical properties And… Application of infrared lens As mentioned, magnesium fluoride nano powder is widely used in the production of infrared lenses. Now, the question that may have arisen for many people is, what are the uses of infrared lenses? In answer to this question, it should be said that infrared lenses are used in cameras and night vision cameras. Currently, in the photography industry, infrared lenses are widely used to create beautiful and special images. Fortunately, with the production of magnesium fluoride nano powder in the country, the production of infrared lenses for use in night vision cameras and photo cameras is done inside the country, and this chemical compound is not imported from any country.
