Ca HK Back-Illumination LED
- Steve Gibson
Table of Contents:
Introduction
This LED is pointed at the fiber block within the HK spectrometer to back-illuminate the fibers. This allows the HK fiber viewing camera in the FIU to determine the locations of the HK fibers.
Because of the small size of the HK fiber block, both the HK science fiber and HK sky fiber are illuminated simultaneously by this LED.
The LED is turned on and off at the PDU outlet using kpfpower for the appropriate outlet.
