Description

Technical Field

[0002] A spectrophotometer is an instrument used to measure the degree of light absorption by a substance. It uses the principles of light interference and diffraction to separate light of different wavelengths and measure their intensities. The spectrophotometer's detection head is a key component of the instrument, receiving optical signals from a sample and converting them into electrical signals for analysis and measurement.

[0003] The technical level of the components of the easily replaceable spectrophotometers currently on the market directly affects the performance and price of the product. The more advanced the technology of the spectrophotometer, the higher its price, but the corresponding measurement accuracy and stability are also better. During operation, the detection head needs to work together with other components of the spectrophotometer, such as the light source, monochromator and data processing system, to complete the entire spectral analysis process. The performance and design of the detection head are crucial to ensuring the overall accuracy and reliability of the spectrophotometer. Therefore, the overall manufacturing cost of a spectrophotometer with a better detection head installed inside is also higher. In order to simplify the operation of detecting samples and detect multiple samples at a time, some spectrophotometers will have multiple detection chambers and correspondingly install multiple detection heads, which makes the overall manufacturing cost of the easily replaceable spectrophotometer higher, which is not conducive to improving the market competitiveness of such easily replaceable spectrophotometers.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a spectrophotometer detection head that is easy to replace. Utility Model Content
