ABSTRACT:
An anti-reflection coating for an optical component and a method of forming the same are disclosed. The anti-reflection coating is formed on a substrate for an optical component by subjecting a mixture of an evaporating material and 10-30% of SiO.sub.2 to vacuum evaporation at room temperature without heating the substrate. When the anti-reflection coating is a single layer, a mixture of MgF.sub.2 and 10-30% of SiO.sub.2 is used as the evaporating material. When the anit-reflection coating is a multi-layer structure, a mixture of a fluoride or a silicon oxide and 10-30% of SiO.sub.2 for a first layer, and a mixture of a fluoride or an oxide and 10-30% of SiO.sub.2 for middle and last layers are used as the evaporating material.
