Abstract
An illumination device includes a light source that emits an electromagnetic radiation input beam, a dichroic first mirror that reflects a first output beam and transmits a second output beam, a second mirror positioned to reflect the second output beam, and an absorber for absorbing radiation emitted by the light source. An adjustable support for the dichroic and second mirror is also provided and is adjustable between a first position where the first beam is transmitted and a second position where the second beam is transmitted, with the other beam being directed to the absorber.
