Abstract
A method, system, apparatus, and/or device to determine a condition of a user using a spectrometer with a collimator on a glass substrate. The method, system, apparatus, and/or device may include: a band comprising a shape, size, and flexibility designed for attaching the band to a body part of a user; a light source embedded in the band that emits light comprising a constituent wavelength that provides an indication of a feature of the body part; an optical sensor positioned in the band to receive the constituent wavelength; and a glass substrate oriented in the band to receive the light, the glass substrate comprising: an optical filter that comprises a passband to isolate the constituent wavelength from other wavelengths of the light; and a carbon nanotube grid structure comprising walls and through-channels, the carbon nanotube grid structure adhered to the glass substrate.
