The P6c offers right angle delivery via a glass prism epoxied within the sleeving. The large area probe uses eight collecting fibres positioned in a ring of diameter 2mm around the central light delivery fibre. A small prism epoxied to the optical fibre provides right angled delivery of light. The prism is held in a disc or hemisphere of 6mm diamter and 2.5 mm height. The probe has eight emmitting and eight collecting fibres equally spaced in a circle of 4mm diameter.
Light is collected from eight tissue sites and integrated into one signal.
Plastic cylinder length is 20mm, diamter 8mm. This is the master connection between the monitor and single fibre detachable probes. It consisits of 1.5m long 1.7mm diameter pvc sleeving containing the transmitting and receiving fibres. Probes attach to the master via an optical inline coupler. These slave probes can be disconnected from the master and left in position in between measurments.
