Abstract: A light source, calibration device and method of calibrating an imaging device is disclose. The calibration device includes the light source which includes an ultraviolet light layer that, in operation, generates ultraviolet light, and a quantum dot layer that absorbs the ultraviolet light and, in response, generates radiation within the near infrared region at a selected intensity. The near infrared light is received at the selected intensity at the imaging device and a sensitivity of the imaging device is altered to detect the near infrared light at the selected intensity provided by the light source.
