ABSTRACT:
A monolithic optical module of injection-molded high temperature polymeric resin combines an optical turn of typically 90 degrees together with dual or triple beam paths. No additional piece parts are necessary for achieving the optical turn, since this occurs by total internal reflection (TIR), and no additional piece parts are necessary for dual monitoring, which is realized by means of an air-gap functioning as a dual beam-splitter plate. The monolithic optical module further includes integrally surfaces for accurate alignment of the module with external optical elements, and can additionally include integral optical elements, for example lenses and thin film coatings.
