Characterization of the LISA Fiber Optic Harness: Modeling the UV Light Transmission in the LISA CMD

The LISA fiber optic harness (FOH) transmits UV LED light onto the LISA test masses to release built up charge from the space environment. A model of the UV light transmission through the FOH and optical feedthrough (OFT) has been developed as an input to an end-to-end simulation of the photoelectric discharging process.
