Summary:This invention provides an improved schlieren optical system for use in analytical ultracentrifuges. The improvement comprises substituting a source of laser light in combination with a focusing lens and a cylinder lens in place of the conventional line source of light in the schlieren optical system. An advantage of the invention is that laser light is more intense than other light and does not require water cooling.
