A jaw assembly including first and second jaw members configured to clamp tissue therebetween. The first jaw member includes a surface opposing a surface of the second jaw member, a light source, and a light detector. The light source is configured to emit light from an opening defined in the surface of the first jaw member. The light detector is disposed within the opening and is configured to sense properties of light reflected off tissue clamped between the first and second jaw members and to generate signals indicative of the sensed properties of light. A processor is operatively associated with the light detector and is configured to receive the signals from the light detector. The processor is also configured to analyze the signals to determine an attribute of tissue clamped between the first and second jaw members and to provide feedback to a user of the attribute of the tissue.
