Abstract
PURPOSE:To almost completely absorb light and to prevent generation of signal noises by forming cupric oxide film of needle state at the inside of a hollow optical guide which consists of cupper or cupper alloys in the inside. CONSTITUTION:The inside of a hollow optical guide which consists of cupper or cupper alloy such as pure cupper, brass, cupper-plated steel or the like in the inside is subjected to anodic oxidation in an aqueous alkaline soln. And it is impregnated in an aqueous alkaline soln. contg. NaClO2 or Na2S2O8. And then it is impregnated in aqueous NH4OH soln. contg. Cu ions. By the above-described method and the like, a cupric oxide film of needle state is formed. By these methods, the film adhered closely is obtained. Whereby a hollow optical guide having the black and good absorptive film of, for example, <=1% reflectivity at 0.63mu wavelength is obtd.
