Abstract

A fiber handpiece developed for dermatological and vascular medical applications is discussed in detail. The handpiece can be zoomed such that it can deliver output spot diameters ranging from 2 mm to 10 mm when connected to a fiber optic with a 365 micrometer diameter core size. The spot diameter is invariant at the treatment plane over a continuous wavelength spectrum between 532 nm to 1064 nm and exhibits a spot diameter variation of less than 10% over the depth of focus of plus or minus 5 mm at each spot size setting. In these regards, the handpiece can be considered 'achromatic' and 'telecentric.' Details of the optical design, the design process, and important delivery device considerations will be discussed.
