Technical Field

[0001] The present application belongs to the technical field of spectrometer manufacturing, and specifically relates to a handheld and portable spectrometer. Background Art

[0002] In the display industry, it is necessary to measure the brightness, chromaticity and color temperature of the display. After the measurement, the spectrometer displays the measurement results for the user to read, but this is real-time reading. The number of measurements and the structure of each measurement cannot be viewed later, which is not convenient for later viewing and analysis. If a data storage device is set in the spectrometer, some heat dissipation structures need to be set up in addition, which increases the size of the spectrometer and makes it inconvenient to carry.

At the same time, since the WIFI module outputs the data to the outside, there is no need to set up a memory inside the shell, thereby reducing the volume of the shell, solving the problem that the current spectrometer is not easy to carry and the measurement data can only be viewed in real time and is not convenient for later viewing and analysis.

[0006] Preferably, the housing is provided with an interface cooperating with the WIFI module.

[0007] Preferably, the lighting lens is equipped with a plano-convex lens with an anti-reflection film.

[0008] Preferably, the size of the display screen is 2.2 inches.

[0020] like Figure 1-3 As shown, a handheld portable spectrometer comprises a shell 1, a lighting lens 2 is provided on the side wall of the shell 1, a WIFI module 3, a CMOS linear array sensor 4, a control main board 5, and an electronic shutter 6 are provided in the shell 1, a display screen 7 is provided on the outer surface of the shell 1, the electronic shutter 6 is provided at the root of the lighting lens 2, the root of the lighting lens 2 is within the sensing range of the CMOS linear array sensor 4, the output end signal of the CMOS linear array sensor 4 is connected to the control main board 5 and the WIFI module 3, and the control main board 5 signal is connected to the display screen 7.

[0021] In this embodiment, when in use, the light signal collected by the lighting lens 2 is focused on the high-precision CMOS linear array sensor 4, and the electronic shutter 6 is used to control the on-off of the light path. Then the CMOS linear array sensor 4 transmits the data to the control mainboard 5, and the test results are displayed on the display screen 7 after being processed by the control mainboard 5, completing a fast and accurate measurement of the brightness and color temperature of the product. The measured data can be wirelessly transmitted to the PC via the WIFI module 3 for storage. During the whole process, the data is not stored in the device in the housing 1, so there is no need to set up a memory in the housing 1, nor is there a heat dissipation device set to dissipate heat from the memory, so the volume of the entire spectrometer will be small. At the same time, since the data is output to the outside of the housing 1 via the WIFI module 3, the data can be stored through an external storage device, which is convenient for later viewing and analysis.

[0022] As a preferred mode, the housing 1 is provided with an interface 8 that cooperates with the WIFI module 3. By providing the interface 8, it is convenient to be used for plugging into a computer (PC end) when outputting data to the outside.

[0023] As a preferred embodiment, the lighting lens 2 is equipped with a plano-convex lens with an anti-reflection film, which has a positive focal length and is suitable for low-brightness testing.

[0024] As a preferred embodiment, the size of the display screen 7 is 2.2 inches.

[0025] As a preferred embodiment, the size of the housing 1 is 46×95×155 mm. As a preferred embodiment, the model of the WIFI module 3 is ESP8266. As a preferred embodiment, the model of the control mainboard 5 is ABX00012.
