The inventive optical mirror includes a substrate, an opaque reflective layer of aluminum, the protective layers of aluminum oxide and cerium oxide. The optical thickness of layers of aluminum oxide and cerium are 0,130 - is 0.135 μm and 0.150 - 0,155 μm, respectively, and the thickness of the layer of aluminum of 0.2 - 0.25 μm. 2 Il. The invention relates to the optical instrument and can be used in the manufacture of reflective elements of different optical devices.Known optical mirror containing a polished substrate of glass and a deposited sequentially by sputtering in a vacuum layer of aluminum on top of it a layer of silicon SiOxwhere 1 < x > 2, a thickness of 1500 (I. T. Cox, . Hass and Hunter WR Appl. Opt, 1975, 14, N 6, S. 1247).The main disadvantages of such mirrors are the low mechanical strength of the corresponding group III according to OST 3-1901-85, and insufficient moisture. Mirrors are destroyed after a one-night stay in a humid atmosphere (90% humidity at 20aboutC). In addition, the reflectivity of the aluminum after applying Plei oblique incidence of the radiation.It is also known an optical mirror containing the polished substrate made of glass and is deposited by sputtering in a vacuum layer of aluminum, protected by a layer of aluminum oxide, also deposited by evaporation in vacuum (I. T Cox and . Hass Appl. Opt 1978, 17 N 14, 333). The main disadvantage of such a mirror is not a high reflectance in the visible region of the spectrum, which is 85% . Other disadvantages are the low mechanical strength of the corresponding group II according to OST 3-1901-85, and low resistance to corrosion - mirror withstand relative humidity 90% at 20aboutAnd with further increase in the temperature and humidity are destroyed.Also known mirror  with a protective coating of oxide of yttrium. On the layer svejenarublennogo of aluminum with a thickness of 600 at a pressure of 2 to 10-5mm RT.article deposited by thermal evaporation from a tungsten boat layer of yttrium oxide thickness 1375 . The disadvantage of this mirror is that the layers of yttrium oxide, deposited by thermal evaporation in vacuum without heating of the substrate is porous and nevlagostoyky. Mirrors can withstand relative humidity 90% at 20aboutAnd with further increase in temperature and humidity (98% at 40about(C) destroyed. Additionally, the proposed technical solution to the technical essence is the design of the mirrors, shown in OST 3-1901-85, sheet 17, containing a substrate of glass K8 and it is on the opaque coating of aluminium of a thickness of 0.1 to 0.15 μm, and the oxide layer of aluminium of a thickness of 0.05 to 0.15 μm, formed by anodic oxidation. The lack of optical mirrors is not sufficiently high reflectance in the visible region of the spectrum 80-86%. Other shortcomings are not enough high moisture resistance, as the mirror can withstand a relative humidity of 85% at 40aboutWith no less than 48 hours, which is insufficient when it is used at high humidity, and low mechanical strength corresponding to the first group, according to OST 3-1901-85 that is not enough when using it in the field.The aim of the invention is to increase the reflection coefficient, mechanical strength, moisture resistance and heat resistance.The aim is achieved in that in the optical mirror containing a substrate, an opaque reflective layer of aluminium of a thickness of 0.20 to 0.25 μm and a protective coating of aluminium oxide thickness 0,130-is 0.135 μm, on top of this layer is applied a layer of cerium oxide thickness 0,150 - 0,155 μm. A significant difference of the mirrors is to perform a protective coating in Vimy thicknesses, this choice of materials from which is made a two-layer protective coating, and the proposed thickness of the layers allows you to increase the reflectivity aluminum mirror in the visible spectrum, to improve the performance characteristics of the mirror.

When applying a layer with a smaller thickness decreases the resistance, and with large thickness - reduced reflectance.
