MoO3 or WO3 can be used as the material receiving low radiant heat. Conventionally, little attention has been paid to MoO3 and WO3 as a material for optical thin films but if these compds, are in a completely oxidized state, it shown no absorption of light and has 1.85-2.0 refraticve index. Thereby, MoO3 and WO3 can be used as a high refractive index material to form an edge filter.

Abstract: PURPOSE:To effectively roughen the surface of electrode material, and increae electrostatic capacitance, by arranging a part of the pass locus of base material, in a space wherein the elevation from the surface end portion of an evaporation source is less than or equal to 30 deg.. CONSTITUTION:That the surface roughness is large can be known from the following; flying-out angle from the evaporation surface depositing continuously metal particles on the base material surface by cathode arc plasma is smaller than 45 deg., or preferably smaller than or equal to 30 deg.. On the bases of the above knowledge about the roughening of a surface, two deposition rolls 3, 3' are arranged at positions passing a space smaller than or equal to 30 deg. from both sides of an evaporation source 22. Microparticles emitted from the evaporation source 22 at a low angle can be deposited on base material 10. Two bath rolls 6, 6' are arranged in the dead angles from the evaporation source 22 which are formed via the rolls 3, 3', and not directly irradiated with the evaporation particles from the evaporation source 22, so that the attaching amount of deposition particles on the surfaces of the bath roll is extremely small. In the case of continuous employment, the possibility of abnormal heating of the base material is avoided because of sufficiently separated detouring from the evaporation source 22.
