Abstract
An apparatus and method, the apparatus comprising; a light collector configured to collect ambient light and provide the collected light to a portion of skin of a user; a photodetector configured to enable a biometric parameter to be monitored by detecting changes in the light absorbed by the portion of skin; and an amplifier configured to amplify an output signal provided by the photodetector; wherein the light collector is configured to filter the collected ambient light to increase the proportion of light within a selected range of wavelengths which is provided to the portion of skin of the user relative to the collected ambient light.
