| Zusammenfassung: | The invention provides a wavelength multiplexing optical device. The wavelength multiplexing optical device comprises a TFF device (1) and a polarization beam-splitting prism device (2); the TFF device (1) multiplexes four optical wavelengths into two optical wavelengths which are multiplexed in pairs in a manner of multiplexing non-adjacent optical wavelengths in pairs, and enables the two optical wavelengths which are multiplexed in pairs to enter the polarization beam-splitting prism device (2); the polarization beam-splitting prism device (2) compounds the two optical wavelengths which are multiplexed in pairs into one optical wavelength in a mutually perpendicular polarizing manner. According to an optical component device provided by the invention, a TFF block multiplexes non-adjacent wavelengths Lambda 1 and Lambda 3, and Lambda 2 and Lambda 4; the bandwidth indicator of a transition zone of a band-pass film can be widened by one time as compared with that of the traditional TFF block; manufacturing di |
