Abstract
A portable spectrometer system is disclosed for more reliable and convenient on-site drug testing. More particularly, but not by way of limitation, the presently disclosed and/or claimed inventive concept(s) relates to a portable spectrometer system having a test strip having a fluorescent indicator, a fluorimeter, and a mobile computing device capable of determining the identity of an unknown substance in the sample.
Claims20
A portable spectrometer system, comprising:
- a fluorimeter comprising:
- a housing having a plurality of interconnected walls at least partially surrounding a cavity, at least one of the interconnected walls being an exterior wall;
- a light source positioned in the cavity and adapted to emit light having a path;
- a support for receiving a test surface having a sample to be analyzed, the support located within the path of the light such that the light contacts the sample to cause an emission from a fluorescent indicator located at the support;
- and
- an optical spectrum separation assembly positioned to:
- receive the emission from the fluorescent indicator, separate the emission into an emission spectrum having a path, and direct the separated emission spectrum through an opening disposed on the exterior wall, the opening located within the path of the separated emission spectrum;
- a mobile computing device comprising:
- an optical sensor positioned to receive the separated emission spectrum passing through the opening and to generate an image indicative of the separated emission spectrum;
- and
- a processor having instructions to analyze the image to determine the identity of an unknown substance within the sample.
