Coatings were designed by Essential Macleod software based on the theory of film.High reflective ZrO 2 -SiO 2 dielectric coating and reflective aluminum coating were made using the design clothes by electron beam heating evap-oration coating method.The reflectivity of dielectric coating is up to rate of95%in wavelength of1.064μm，and the av-erage reflectivity of aluminum coating is over 95% between 3 μm and 5 μm. The technical parameters and environmental adaptability of the film are excellent.
