Abstract
Henry Draper described the use of flexible bands to minimize optical surface deflection of mirrors mounted in the optical axis horizontal position in 1864. Despite this historical background the theoretical basis for horizontal band support was not developed until quite recently. Use of finite element analysis has led to a better understanding of the performance of horizontal band supports. Analytical modeling of horizontal band supports has resulted in improvements in design. In particular the use of roller chains as a horizontal support significantly reduces the deflection of an axis horizontal large mirror. Providing that certain design precautions discussed in this paper are taken roller chains provide a relatively simple and low cost support. A number of successful roller chain supports for optics from 0. 68 m to 1 . 8 m in diameter have been built based on the results of the above analytical models. 2.
