Abstract
Optical systems are disclosed for use in identifying an analyte, such as glucose in blood or interstitial fluid (ISF), using a biomaterial, such as glucose binding protein (GBP), that is brought into contact with the analyte. An optical system includes a first filter adapted to reflect light emitted from a light-emitting diode to illuminate a fluorescent body, and further adapted to transmit light emitted from the fluorescent body, and a second filter adapted to separate light transmitted by the first filter into signal band light and reference band light.
