Abstract
Description
technical field
[0001] The invention relates to a polymer composition, in particular to an infrared-transmitting polymethyl methacrylate composition. Background technique
[0002] After Newton obtained the solar spectrum with a prism, after more than a hundred years, the British astronomer W. Herschel, in his experiment on the thermal effect of the solar spectrum in 1800, found that the maximum position of the thermal effect is at the infrared end of the visible spectrum. Called "invisible light" then, by 1835 Ampere called it infrared. Infrared is also a kind of electromagnetic wave, and its wavelength is between 0.75 and 1000 μm.
[0003] In different research fields such as military, space, industrial technology, etc., according to the different generation mechanisms, transmission characteristics and detection methods of infrared radiation, and considering the specific window of infrared transmission in the atmosphere (that is, the corresponding transparent band in the e...
