Solar Bolometric Imager
STATUS
Being Refurbished
AVAILABILITY
Carried aboard a balloon borne gondola, this telescope will probably have a two week flight each 5th year. The next flight is in 2008. Interested scientists are welcome to contact us

Solar Instruments
A 30 cm solar telescope with uncoated mirrors forms an image of the sun at the focal plane of a heat-imaging camera, 240 pixels x 360 pixels. The sensor is coated with gold black, which absorbs all wavelengths and emits 8 - 10 micron radiation (heat) in proportion to the energy in the solar light striking each pixel. The pixel to pixel calibration is precise enough to reveal any important variations in radiative output by features on the solar disk.
