The Large Area Imager for the Wise Observatory -
LAIWO, is an optical camera with 4 CCDS 4Kx4K pixels,
currently being built here at the Max-Planck-Institut fuer Astronomie,
Heidelberg. The camera will be mounted on the 1-m telescope in the Wise Observatory in the Negev
desert, Israel. The field of view will be one square degree with a
0.7'' resolution. LAIWO will be used for photometric detection of
transiting extra-solar Jupiter-size planets.
will have 4
Lockheed CCD486 devices, 4kx4k pixels, each 15 microns. The CCDs
are frontside-illuminated with the following characteristics:
There will be one guider CCD located at the center of the mosaic: a eV
CCD47-20, 1kx1k frame transfer device, with a pixel size of 13 microns.
The filters (B,V,R,I,z') will be mounted on a ruler that fits into a drawer. Three
separate plates of sets of filters can be mounted on the ruler at the
same time. Each plate contains 5 filters, 4 for the imager CCDs and one
for the guider CCD.
- Quantum Efficiency of about 40% between 600 and 850nm
- Read-out noise < 5 e-
- Full-well > 85,000 e-
The Wise telescope is a Boller and
Chivens telescope, i.e. a Ritchey-Chretien reflector mounted on a rigid
off-axis equatorial mount. The optics consist of:
The Wise Observatory is located 200 km South of Tel Aviv, Israel and 5km West of the city of Mitzpe
Ramon in the Negev desert.
- a 40 inch/1m diameter clear aperture f/4 primary
- a 20 inch/50cm diameter f/7 Cassegrain secondary
- a corrector quartz lens located 4 inch/10 cm above
