Patent ID: 7299080

Claim:
An apparatus for noninvasive measurement of glucose through near-infrared spectroscopy, comprising: a base module comprising a grating and a detector array; a sampling module, configured to be securely and removeably attached to a sample site, and coupled to said base module, said sampling module comprising an illumination source; an optic system configured to be located before and/or after said sample site for coupling said illumination source to said sample and said sample to said detector array; an optical filter configured to be located between said illumination source and said sample site, wherein said optical filter comprises: a silicon filter for removing light under 1050 nm, wherein said grating can be used in the 1150 to 1850 nm region without detection of second or higher order light off of said grating, and a communication bundle for carrying optical and/or electrical signals between said base module and said sampling module, and for carrying power to said sampling module from said base module.
