An optical apparatus applied to ophthalmology detection is disclosed. The optical apparatus includes a first light source module, a second light source module, and an interference module. The first light source module is formed by fiber units and lens units and used to emit a first light signal. The second light source module is formed by fiber units and lens units. The second light source module is coupled to the first light source module in series. The second light source module is used to receive a first light signal and emit a second light signal. The interference module is coupled to the second light source module and used to receive the second light signal and provide a first incident light and a second incident light to an object to be detected and a reference mirror respectively.本發明揭露一種應用於眼科檢測之光學裝置。光學裝置包含第一光源模組、第二光源模組及干涉模組。第一光源模組係由光纖單元及透鏡元件構成。第一光源模組係用以發出第一光訊號。第二光源模組係由光纖單元及透鏡元件構成。第二光源模組係與第一光源模組串接。第二光源模組用以接收第一光訊號並發出第二光訊號。干涉模組係與第二光源模組耦接,用以接收第二光訊號並分別提供第一入射光及第二入射光至待測物及參考反射鏡。1‧‧‧光學裝置10‧‧‧第一光源模組12‧‧‧第二光源模組14‧‧‧干涉模組RM‧‧‧參考反射鏡OD‧‧‧待測物N1‧‧‧第一光訊號N2‧‧‧第二光訊號L1‧‧‧第一入射光L2‧‧‧第二入射光
