Abstract: A spectrometer includes an input unit for receiving an optical signal, a diffraction grating disposed on the transmission path of the optical signal for dispersing the optical signal into a plurality of spectral rays, an image sensor disposed on the transmission path of at least a portion of the spectral rays, and a waveguide device. A waveguide space is formed between the first and second reflective surfaces of the waveguide device. The optical signal is transmitted from the input unit to the diffraction grating via the waveguide space. The portion of the spectral rays is transmitted to the image sensor via the waveguide space. At least one opening is formed on the waveguide device, and is substantially parallel to the first and/or second reflective surface. A portion of the spectral rays and/or the optical signal diffuses from the opening out of the waveguide space without reaching the image sensor.

Abstract: The present application discloses an optical sensing module, an optical mechanism of a spectrometer, and a spectrometer. An optical sensing module according to one embodiment comprises an optical sensing component and an optical fiber. The optical sensing component includes at least a row of optical sensing units. The optical fiber is made of a transparent material and has a cylindrical curved surface. A side of the cylindrical curved surface faces the optical sensing units to converge at least a portion of an incident light received by the optical sensing units. With techniques of the present application, the amount of light collected at the optical sensing component can be increased for it to be suitable for applications such as miniaturized apparatuses and systems, thus improving the overall efficiency of optical reception and utilization therein.

Abstract: An optical head for receiving incident light is provided. The optical head comprises a transmissive cosine corrector and a reflector disposed to face the transmissive cosine corrector. The transmissive cosine corrector is disposed in an optical path of the incident light and shields the reflector from the incident light. The transmissive cosine corrector converts the incident light to scattered light having a Lambertian pattern. The reflector has an optical output section that transmits the scattered light and a reflective section that reflects the scattered light to the transmissive cosine corrector and/or the other portions of the reflective sections. An optical system using the optical head is also provided.
