Optical thin-film-forming methods are disclosed that form optical thin film on a base plate arranged in a vacuum chamber. An exemplary method includes the steps of retaining the base plates on a plurality of retaining frames of a base-plate retainer, heating the base plate, and emitting a deposition material from a deposition source. The retaining frames are configured to make the entire base plate uniformly heated.
