Abstract

The need for improved means of beam attenuation in uv optical damage experiments has led to the development of a new reflective attenuator using conventional multilayer dielectric optics. The device has low insertion loss even for unpolarized beams, high damage resistance, continuously variable attenuation, and a large clear aperture. Also discussed is a transmissive version of this device which uses standard reflectors or edge filters. Either version lends itself well to computer automation.
