Abstract

PURPOSE: To obtain a reflection preventing film with high endurance even if MgF2 is vapor deposited at a relatively low temp. by forming a metal layer on an Al2O3 layer and further forming an MgF2 layer as the uppermost layer.
CONSTITUTION: For example, white plate glass 30 is heated to 200°C and plasma treated under 1×10-5 Torr, and Al2O3 layer 31, ZrO2 layer 32, Al2O3 layer 33, Cr layer 34 and MgF2 layer 35 are vapor deposited with electron beams in order. A reflection preventing film may be formed on a transparent synthetic resin such as a diethylene carbonate lens as follows: SiO2 layer 51, Al2O3 layer 52, ZrO2 layer 53, Al2O3 layer 54 and Mo layer 55 are vapor deposited on lens 50 in order by heating with electron beams without especially heating substrate 50, and MgF2 layer 56 is coated in Ar plasma under 4×10-5 Torr. Thus, by forming the MgF2 layer on the combined Al2O3 and metal layers at about 200°C, a reflection preventing film with superior hardness, weather resistance, etc. is obtd. even on such a plastic substrate.
