Classification: CPC G | IPC G

Claim 0:
1. A Raman scattering measurement apparatus comprising:
a light source which emits light to smoke particles;
a filter configured to block light which is incident to the smoke particles and passes through the particles, and to allow Raman scattered light to pass therethrough;
a nanoimprint filter configured to secondarily filter the Raman scattered light passing through the filter and to send the Raman scattered light to the photodetector; and
a photodetector which detects the Raman scattered light passing through the nanoimprint filter,
wherein the nanoimprint filter is configured to decrease a predetermined wavelength range of a detection sensor constituting the photodetector by limiting a range of a wavelength of the Raman scattered light to correspond to a detection characteristic of the photodetector.
