ABSTRACT:
Provided is a method for making a thin film on a lens holder to reduce a reflection of light caused by an index difference between a refractive index of air and a refractive index of a lens-barrel of the lens holder. The thin film is formed by dipping the lens holder into a solution of a solvent and a fluororesin compound or by dripping the solution onto the lens holder. The lens holder is removed from the solution. Then, the solvent is removed to thereby form a thin film of the fluororesin compound on the lens holder.
