>Warner & Swasey during the period of 1886 to 1916 or 1917 were likely to have
>Brashear optics with some exceptions.
>Especially important is information regarding the uses of the instruments as
>well as discoveries or historically important research that was done using
>them. For example, Dr. Brashear made the plane mirrors for A. A. Michelson's
>interferometer used to determine standards of measurement using wavelengths
>of monochromatic light. Another notable instrument was George E. Hale's
>spectroheliograph, first produced by Brashear.
