Abstract:
First, a box 5 molded from a resin is prepared such as to have a rectangular parallelepiped outer form with a pair of grooves on the bottom face and a semispherical recess 9. Subsequently, a photocurable resin agent 27 is applied to a bottom area 12 of the recess 10 in the box 5. Then, while a light transmitting mold 28 having a bottom face formed with a plurality of grating grooves arranged in a row along a predetermined direction is pressed against the applied resin agent 27, the resin agent 27 is cured by irradiation with light, so as to provide the area 12 in the recess 10 with the grating 29 formed with a plurality of grating grooves. Next, Al, Au, or the like is vapor-deposited so as to cover the grating 29, thereby forming a reflecting film 15. Then, a photodetector 4 is accommodated in a package 2. This can easily manufacture a highly reliable spectrometer.
Abstract:
In the spectroscopy module 1, a light absorbing layer 6 having a light-passing hole 6a through which light L1 advancing into a spectroscopic portion 3 passes and a light-passing hole 6b through which light L2 advancing into a light detecting portion 4a of a light detecting element 4 passes is integrally formed by patterning. Therefore, it is possible to prevent deviation of the relative positional relationship between the light-passing hole 6a and the light-passing hole 6b. Further, since the occurrence of stray light is suppressed by the light absorbing layer 6 and the stray light is absorbed, the light detecting portion 4a of the light detecting element 4 can be suppressed from being made incident. Therefore, according to the spectroscopy module 1, it is possible to improve the reliability.
Abstract:
The present subject matter relates to methods of high-speed analysis of product samples. Light is directed to a portion of a product under analysis and reflected from or transmitted through the product toward an optical detector. Signals for the detector are compared with reference signals based on a portion of the illuminating light passing through a reference element to determine characteristics of the product under analysis. The products under analysis may be stationary, moved by an inspection point by conveyor or other means, or may be contained within a container, the container including a window portion through which the product illuminating light may pass.
