Abstract
An embodiment of a light launching portion of a photoplethysmographic device having a laser (20) light source and a light guide (40). The coupled end of the light guide (40) includes an anti-reflection coating (30a) to prevent or minimize the back reflection of light emitted by the laser (20). This minimizes the extent to which back reflected light can re-enter the laser and adversely alter the optical output properties of the laser (20) and additionally minimizes the associated light loss thus helping to maximize the optical coupling efficiency. Other embodiments are described and shown.
