Brief description of LDSS3

12

 

LDSS stands for `Low Dispersion Survey Spectrograph'. LDSS-3 excels at obtaining spectra of large numbers of faint objects. Its high throughput and excellent sky subtraction lead to spectacular performance at very faint limits while its relatively large field of view and multiobject capability provide a large multiplex advantage for statistical projects.

The original LDSS-2 arrived in Chile at the end of March, 2001. An engineering run on Magellan I occurred on April 8-12, 2001, and the first scientific use was on April 13, 2001. The optics were redesigned by Mike Gladders and replaced in February, 2005. We are calling the current version of the instrument LDSS-3 to distinguish it from the earlier version.
