Abstract

A lens system for use with photoacoustic microscopy apparatus has a collimated single mode optical fiber to which a toroidal ultrasound transducer is operatively attached. The transducer is located inside a tank. A lens housing is located inside the tank adjacent the transducer and has flexible optically transmissive entrance and exit ports made of polydimethysiloxane. The lens housing is filled with cinnamaldehyde. The cinnamaldehyde can be introduced into the lens housing and withdrawn from it so as to flex its entrance and exit ports, and the tank is filled with a mixture of glycerol and water.
