| Pick-Off
Mirror |
Mirror that directs light from Hubble's focal plane
into WFC3's optics. |
| Instrument
Enclosure |
WFC3's
primary casing and framework for its mechanical and
electronic parts. It is made mostly of aluminum 6061. |
| Optical
Bench |
Structure that contains WFC3's optics. The bench is
made of a Graphite CySi/Aluminum alloy. |
| Radiator

All
of Hubble's power is supplied by its solar panels and
stored in batteries. The LVSP routes Hubble's power
into WFC3. |
| CEB
- CCD Electronics Box |
Contains
the electronics for the UVis channel's Charged Couple
Device (CCD). |
