| titleOfInvention | Optical equipment and prism |
| abstract | A prism having a small phase difference between s-polarized light and p-polarized light before and after reflection of an incident light beam and an optical device having the prism are provided. A prism having a pair of reflecting surfaces intersecting at a nominal surface angle of 90 °. And an optical apparatus having an observation optical system comprising at least one lens, wherein the prism is arranged such that a ridge line of the pair of reflection surfaces divides a pupil of the observation optical system, The pair of reflecting surfaces of the prism includes (a) a dielectric multilayer film composed of at least two dielectric films, and (b) a metal film laminated on the dielectric multilayer film. The multilayer optical film is an optical apparatus characterized in that adjacent dielectric films have different refractive indexes, and each dielectric film has an optical film thickness of 5 nm or more.
