Abstract
Small and simple ultra-violet interferometer is designed. The interferometer consists of very small ball and concave mirrors. The interferometer can be tested in a vacuum chamber or in space for ultra-violet region for better precision. Interferometer can be used in a very large spectral region as it consists of mirror surfaces only. It is possible to use the interferometer to test optics of a space interferometer or a space telescope. These interferometers are very cheap and easily can be manufactured in quantity. Interferometers are very small that is why they are especially recommended for testing optics in space.
