Description

technical field [0001] The invention relates to the technical field of optical measurement, in particular to an optical measurement system. Background technique [0002] There are two ways of coupling the sensor chip and the optical path used by the existing SPR detector using Kretschmann structure modulation. However, most of the current production methods use artificial grinding or plastic injection molding. Neither of these two production methods can solve the problem of batch differences and production costs. At present, this method is only used on the first-generation SPR detector; the second method The method is to drop a liquid substance such as cedar oil between the optical prism and the chip substrate to solve the problem of optical transmission between the two media. The operation is cumbersome, the automation of the detection cannot be realized, and the bubbles that interfere with the detection cannot be completely eliminated when the two media are adhered after ...

Problems solved by technology

[0002] There are two ways to couple the sensor chip and the optical path used in the existing SPR detectors modulated by the Kretschmann structure: one conventional approach is to use an integrated structure of optical prisms and chips, because optical prisms require high precision and high stability However, most of the current production methods use manual grinding or plastic injection molding. These two production methods cannot solve the problems of batch differences and production costs. At present, this method is only used on the first generation of SPR detectors; the second method The method is to drop liquid substances such as cedar oil between the optical prism and the chip substrate to solve the problem of optical transmission between the two media. The problem that arises in this way is that it needs to be added manually every time the chip is used, causing the entire The operation is relatively cumbersome, and the automation of the detection cannot be realized, and the air bubbles that interfere with the detection cannot be completely eliminated when the two media are bonded after each drop, resulting in the problem of detection failure.
