Abstract in simplified Chinese:一种可操作于波长范围为4.5微米或4.5微米以上的小型光谱仪,其包括一入射狭缝、一准直镜、一光栅、一聚焦镜以及一第一聚焦面。通过此狭缝的部分辐射会沿着一光径行进,在此光径中,此通过狭缝的部分辐射会被准直镜反射到光栅上,按着此光栅反射部分辐射到聚焦镜,而后该聚焦镜便会反射与聚焦部分辐射在第一聚焦面及二维数组侦测器之上。二维数组侦测器中每一行均对应到波长范围为4.5微米或4.5微米以上的某个波长,此二维数组包括复数行,其全部会对应到横跨波长范围为4.5微米或4.5微米以上的复数个波长,且在此二维数组侦测器上每一对相邻的行均对应到波长差相等的两波长。此入射狭缝、准直镜、光栅、聚焦镜以及第一聚焦面系置放于一大小等于或小于192立方英吋的体积内。
Abstract:
An absolute transmission accessory for a spectrometer. One example spectrometer system includes a base plate, a light source configured to transmit light, and an interferometer mounted to the base plate. The interferometer receives the light from the light source and output modulated light. The spectrometer system includes a first optical element configured to receive the modulated light and direct the modulated light, and a second optical element configured to receive the modulated light and focus the modulated light to a sample compartment. The spectrometer system includes a detector compartment including one or more detectors, the detector compartment configured to receive light from the sample compartment. The spectrometer system includes a sample holder coupled to the base plate. The modulated light is directed to the sample holder, and light exiting the sample holder is directed through the sample compartment and to the detector compartment via the second optical element.

Abstract:
A spectroscopic assembly (165) may include a spectrometer (110). The spectrometer may include an illumination source to generate a light to illuminate a sample. The spectrometer may include a sensor to obtain a spectroscopic measurement based on light, reflected by the sample, from the light illuminating the sample. The spectroscopic assembly may include a light pipe (120) to transfer the light reflected from the sample. The light pipe may include a first opening (146) to receive the spectrometer. The light pipe may include a second opening (148) to receive the sample, such that the sample is enclosed by the light pipe and a base surface when the sample is received at the second opening. The light pipe may be associated with aligning the illumination source and the sensor with the sample.
Abstract:
The invention relates to an arrangement for the spectrometric measurement of products such as cereals, oleaginous products or derived products. According to the invention, the arrangement is characterised in that it comprises a mechanism (17, 18, 19) for the selective adjustment of the position of the light beam in the vertical and horizontal planes, and a selective adjustment device for ensuring the parallelism of the rays of the light beam. The invention is especially applicable to the area of cereals.
Abstract:
In a spectroscopic module 1, a flange 7 is formed integrally with a diffraction layer 6 along a periphery thereof so as to become thicker than the diffraction layer 6. As a consequence, at the time of releasing a master mold used for forming the diffraction layer 6 and flange 7, the diffraction layer 6 formed along a convex curved surface 3a of a main unit 3 can be prevented from peeling off from the curved surface 3 a together with the master mold. A diffraction grating pattern 9 is formed so as to be eccentric with respect to the center of the diffraction layer 6 toward a predetermined side. Therefore, releasing the mold earlier from the opposite side of the diffraction layer 6 than the predetermined side thereof can prevent the diffraction layer 6 from peeling off and the diffraction grating pattern 9 from being damaged.
