What kind of cameras are used in the hubble telescope?

Answer 1

Wide Field/Planetary Camera 2
The original Wide Field/Planetary Camera (WF/PC1) was changed out and displaced by WF/PC2 on the STS-61 shuttle mission in December 1993. WF/PC2 was a spare instrument developed in 1985 by the Jet Propulsion Laboratory in Pasadena, California.

WF/PC2 is actually four cameras. The relay mirrors in WF/PC2 are spherically aberrated to correct for the spherically aberrated primary mirror of the observatory. (HST's primary mirror is 2 microns too flat at the edge, so the corrective optics within WF/PC2 are too high by that same amount.)

The "heart" of WF/PC2 consists of an L-shaped trio of wide-field sensors and a smaller, high resolution ("planetary") camera tucked in the square's remaining corner.


Corrective Optics Space Telescope Axial Replacement
COSTAR is not a science instrument; it is a corrective optics package that displaced the High Speed Photometer during the first servicing mission to HST. COSTAR is designed to optically correct the effects of the primary mirror's aberration on the three remaining scientific instruments: Faint Object Camera (FOC), Faint Object Spectrograph (FOS), and the Goddard High Resolution Spectrograph (GHRS).


Faint Object Camera
The Faint Object Camera is built by the European Space Agency. It is the only instrument to utilize the full spatial resolving power of HST.

There are two complete detector system of the FOC. Each uses an image intensifier tube to produce an image on a phosphor screen that is 100,000 times brighter than the light received. This phosphor image is then scanned by a sensitive electron-bombarded silicon (EBS) television camera. This system is so sensitive that objects brighter than 21st magnitude must be dimmed by the camera's filter systems to avoid saturating the detectors. Even with abroad-band filter, the brightest object which can be accurately measured is 20th magnitude.

The FOC offers three different focal ratios: f/48, f/96, and f/288 on a standard television picture format. The f/48 image measures 22 X 22 arc-seconds and yields resolution (pixel size) of 0.043 arc-seconds. The f/96 mode provides an image of 11 X 11 arc-seconds on each side and a resolution of 0.022 arc-seconds. The f/288 field of view is 3.6 X 3.6 arc- seconds square, with resolution down to 0.0072 arc-seconds.

Answer 2

More precisely, the Hubble Telescope IS a camera that uses a variety of sensors to observe various optical wavelengths, most of which are CCD.

Answer 3

Hi. Hubble uses CCD cameras. http://blogs.physicstoday.org/newspicks/2006/07/hubble_camera_back_online.html
