Abstract
A spectrometer includes a light conduit configured to align scattered light scattered in a target by light output from a light source into a collimated beam, and a beam block configured to restrict an angle of the scattered light and detect the scattered light via the light conduit or the beam block through a filter array and a detector, thereby achieving miniaturization in a pen type or a flat plate shape while maintaining a spectral characteristic.
Claims24
A spectrometer comprising:
- a light source configured to emit a light to a target;
- a light conduit comprising a measurement hole through which the light scattered by the target is incident, an inner surface configured to condense the light incident on the measurement hole into a collimated beam, and an output hole configured to output the light condensed by the inner surface;
- a detector configured to detect the light output from the output hole of the light conduit;
- and
- a filter array comprising filters arranged on a detection surface of the detector and transmitting a predetermined wavelength band of the light output from the output hole of the light conduit.

A spectrometer comprising:
- a light source configured to emit a light to a target;
- a light detector configured to detect the light that returns from the target;
- a beam splitter that is disposed between the light detector and the target, and configured to change a direction of the light emitted from the light source so that the light travels toward the target;
- a light conduit that protrudes from an outer surface of the spectrometer, extends in the changed direction of the light, and comprises a hole through which the light having the changed direction exits the spectrometer.
