Abstract
An apparatus with a combination of a point light source and a single lens is provided. The present apparatus includes a point light source, a photodetector and a lens. The lens is placed in the same side of the point light source and the photodetector in order that the light emitting from the point light source is focused onto a target area of an object through the lens. The reflected light from the target area is focused onto the photodetector through the lens. The present apparatus can qualitatively and quantitatively monitor a content of a specific component of a tested solution. The geometric relationship of the point light source, the photodetector and the single lens can improve a measuring resolution of the present apparatus.
Claims20
An apparatus, comprising:
- one or more light sources configured to irradiate a test apparatus comprising a test sample with a first wavelength and a second wavelength;
- one or more photodetectors configured to receive a first reflected light comprising the first wavelength and to receive a second reflected light comprising the second wavelength;
- and
- a processor configured to analyze the first reflected light to determine a sampling amount of the test sample comprising a specific component, wherein the processor is further configured to analyze the second reflected light to determine a concentration of the specific component in the test sample.
An apparatus, comprising:
- means for irradiating a test sample applied to a test apparatus, wherein the test sample is irradiated with both a first wavelength and a second wavelength;
- means for receiving a first reflected light comprising the first wavelength, wherein the means for receiving is further configured to receive a second reflected light comprising the second wavelength;
- means for analyzing the first reflected light to determine a sampling amount of the test sample comprising a specific component;
- and
- means for analyzing the second reflected light to determine a concentration of the specific component in the test sample.
