First Claim
Patent Images
1. A seeker, comprising:
- a first receiver configured to receive an infrared signal;
a second receiver configured to receive a radio frequency signal;
a dichroic mirror configured to reflect the infrared signal toward the first receiver and to transmit the radio frequency signal toward the second receiver, wherein the dichroic mirror includes a material that transmits the radio frequency signal and reflects the infrared signal, the material having a softening temperature of less than or equal to 600°
C. and a dielectric constant of less than or equal to 4, and wherein the dichroic mirror is made by molding the material to form the dichroic mirror.
