Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0023] Example 1:

[0024] This utility model provides a technical solution: a spectrometer for detecting pulsed ultraviolet radiation intensity, comprising a spectrometer body, characterized in that: the spectrometer body includes a power supply module, an optical acquisition module, a photoelectric detection module, a beam splitting module, a display module, and a signal processing and control module; the power supply module is electrically connected to the optical acquisition module, photoelectric detection module, beam splitting module, display module, and signal processing and control module via wires; the optical acquisition module includes a condenser lens and an aperture, used to collect and collimate the light emitted by the pulsed ultraviolet disinfection lamp, ensuring efficient light transmission to the beam splitting module; the power supply module wires provide power support to the other modules; the optical acquisition module collects light signals and transmits them to the beam splitting module; the light signals processed by the beam splitting module are received by the photoelectric detection module; the output signal of the photoelectric detection module is transmitted to the signal processing and control module for processing, and the processing result is then transmitted to the display module for display. By adopting the above technical solution, the optical acquisition module consists of high-quality lenses and optical filters, which can effectively collect pulsed ultraviolet light and reduce stray light interference. The beam splitting module uses grating beam splitting technology to decompose the light signal into light of different wavelengths. Through a high-precision grating or prism, the composite light can be decomposed into monochromatic light of different wavelengths and projected onto the photoelectric detection module. The photoelectric detection module uses an InGaAs detector, which has high sensitivity and fast response characteristics, and can quickly and accurately convert the light signal into an electrical signal and transmit it to the signal processing and control module. The signal processing and control module uses a high-speed data acquisition card and a microprocessor to amplify, filter, and perform analog-to-digital conversion on the electrical signal, realizing the acquisition, processing and analysis of the electrical signal, and calculating the irradiance and effective dose according to the preset program. The display module uses an LCD screen to intuitively display the detection results, including the irradiance value of each wavelength, the effective dose value, and related spectral curves. The power supply module maintains a regulated power supply to ensure the normal operation of each module.

[0025] Example 2:

[0026] Based on Example 1.

[0027] Specifically, the photoelectric detection module includes multiple photodetectors, the signal processing and control module includes a high-speed data acquisition card and a microprocessor, and the display module includes a liquid crystal display screen. By employing the above technical solution, the light emitted by the pulsed ultraviolet disinfection lamp is decomposed into monochromatic light of different wavelengths using a high-speed photodetector. Then, an InGaAs-10MHz photodetector converts the optical signal into an electrical signal. Through the acquisition, amplification, and processing of the electrical signal, combined with a pre-set wavelength range, the irradiance intensity of each wavelength within that range is accurately measured, and the effective dose is calculated according to a specific algorithm, thereby comprehensively and accurately evaluating the disinfection capability of the pulsed ultraviolet disinfection lamp.

[0028] The working principle of this invention is as follows: In use, the focusing lens in the optical acquisition module is made of quartz, which has excellent ultraviolet light transmittance and focusing performance. The aperture is made of stainless steel, and precision machining ensures the accuracy and smoothness of the aperture. The grating or prism in the beam splitting module is selected according to the required wavelength resolution and beam splitting range to ensure the accuracy and stability of the beam splitting effect. The photodetector in the photoelectric detection module is selected according to different wavelength response ranges, and its anti-interference capability is improved through optimized circuit design and shielding measures. The high-speed data acquisition card and microprocessor in the signal processing and control module are mature products selected from the market to ensure the speed and accuracy of data processing. During the assembly process, each component uses a high-precision mechanical structure and optical adjustment device to ensure the collimation and stability of the optical path, reducing the loss and error of the optical signal. A high-precision spectral splitting element decomposes the light emitted by the pulsed ultraviolet disinfection lamp into monochromatic light of different wavelengths, and then a high-sensitivity photodetector converts the optical signal into electrical signals. The instrument, through the acquisition, amplification, and processing of electrical signals, combined with a pre-set wavelength range (200nm-300nm), accurately measures the irradiance of each wavelength within this range and calculates the effective dose according to a specific algorithm, thereby comprehensively and accurately evaluating the disinfection capability of the pulsed ultraviolet disinfection lamp. After the instrument is assembled, it is calibrated and standardized using a standard ultraviolet light source with known irradiance and spectral distribution. By adjusting the parameters of the signal processing and control module, the measurement results of the instrument are matched with the actual values ​​of the standard light source, ensuring the accuracy and reliability of the detection. The instrument is calibrated and maintained regularly. Standard filters and attenuators are used to test and adjust the wavelength accuracy, irradiance linearity, and other indicators of the instrument, ensuring stable and reliable performance during long-term use. The optical acquisition module acquires pulsed ultraviolet light, which is processed by the spectrophotometer and photoelectric detection modules. The signal processing and control module calculates the irradiance and displays the results through the display module, thus completing the pulsed ultraviolet measurement operation.
