Optical thin-films are disclosed that are formed from optical thin films formed on a base plate arranged in a vacuum chamber. The base plates are held on a plurality of retaining frames of a base-plate retainer. The thin films are formed by 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.
