Optical attenuator

Claim 1

A LIGHT ATTENUATOR WHICH COMPRISES: A HOUSING, A PRISMOID IN SAID HOUSING, SAID PRISMOID INCLUDING A LIGHT INLET END AND A LIGHT OUTLET END EXTENDING FROM SAID HOUSING, A FIRST LIGHT REFLECTING-REFRACTING SURFACE IN OPTICAL ALIGNMENT WITH SAID INLET END, A SECOND LIGHT REFLECTING-REFRACTING SURFACE IN OPTICAL ALIGNMENT WITH SAID FIRST REFLECTING-REFRACTING SURFACE WHICH RECEIVES LIGHT REFLECTED FROM SAID FIRST SURFACE, A THIRD LIGHT REFLECTING-REFRCTING SURFACE IN OPTICAL ALIGNMENT WITH SAID SECOND REFLECTING-REFRACTING SURFACE WHICH RECEIVES LIGHT REFLECTED FROM SAID SECOND REFLECTING-REFRACTING SURFACE, A FOURTH LIGHT REFLECTING-REFRACTING SURFACE IN OPTICAL ALIGNMENT WITH SAID THIRD REFLECTING-REFRACTING SURFACE WHICH RECEIVES LIGHT REFLECTED FROM SAID THIRD REFLECTING-REFRACTING SURFACE, SAID FOURTH REFLECTING-REFRACTING SURFACE REFLECTING LIGHT OUT THROUGH SAID OUTLET END OF SAID PRISMOID, A FIRST WINDOW IN SAID HOUSING, A FIRST MIRROR SURFACE WITHIN SAID HOUSING, SAID FIRST MIRROR SURFACE POSITIONED TO RECEIVE LIGHT REFRACTED FROM SAID FIRST REFLECT-REFRACTING SURFACE AND TO REFLECT INCIDENT LIGHT OUT OF SAID HOUSING THROUGH SAID FIRST WINDOW IN SAID HOUSING, SAID SECOND REFLECTING-REFRACTING SURFACE REFRACTING LIGHT OUT THROUGH SAID FIRST WINDOW IN SAID HOUSING, A SECOND WINDOW IN SAID HOUSING, A SECOND MIRROR SURFACE WITHIN SAID HOUSING, SAID SECOND MIRROR SURFACE POSITIONED TO RECEIVED LIGHT REFRACTED FROM SAID THIRD REFLECTING-REFRACTING SURFACE AND TO REFLECT INCIDENT LIGHT OUT OF SAID HOUSING THROUGH SAID SECOND WINDOW IN SAID HOUSING, SAID FOURTH REFLECTING-REFRACTING SURFACE REFRACTING LIGHT OUT THROUGH SAID SECOND WINDOW IN SAID HOUSING, AND AN OPTICAL SOLUTION WITHIN SAID HOUSING AND SURROUNDING SAID PRISMOID, SAID OPTICAL SOLUTION HAVING AN INDEX OF REFRACTION WHICH IS LESS THAN THE INDEX OF REFRACTION OF SAID PRISMOID.
