The measurement range generally includes the visible light region with a wavelength range of 380 to 780 nm and the ultraviolet light region with a wavelength range of 200 to 380 nm. Different light sources have their own unique emission spectra, so different illuminants can be used as the light source of the instrument. The emission spectrum of a tungsten lamp: the spectral light with a wavelength of 380 to 780 nm emitted by a tungsten lamp light source is refracted through a prism to obtain a continuous color spectrum composed of red, orange, yellow, green, blue, indigo, and purple; this color spectrum can be used as the light source of a visible light spectrophotometer. However, in the prior art, the mechanical structure of the spectrophotometer is complex, and it is easy to produce mechanical vibration and thermal interference; the optical system is difficult to assemble, and it is easy to produce optical distortion, which affects the imaging quality; the assembly process is cumbersome, and it is easy to produce assembly errors, which affects the product quality; the manufacturing cost is high, resulting in a relatively expensive product price.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 - Figure 4 A spectrophotometer bottom plate assembly comprises a bottom plate 1, wherein the bottom plate 1 is connected to a back plate 2; the bottom plate 1 comprises a reinforcing rib module 3, a sample chamber module 4 is arranged on the reinforcing rib module 3, a main control board module 5 is arranged adjacent to the sample chamber module 4, a switching power supply module 7 is arranged above the main control board module 5, and a monochromator module 6 is arranged adjacent to the switching power supply module 7; a main control board hole 10, a fan hole 11, a lamp chamber cover hole 8 and a power socket hole 9 are arranged in sequence from left to right or from top to bottom on the back plate 2.

[0027] It should be noted that the base plate 1 is formed by injection molding into a mold, and the sample chamber module 4, the monochromator module 6 and the switching power supply module 7 are integrated at the same time. The main components such as the sample rack, the monochromator, and the power supply can be directly installed on the sample chamber module 4, the monochromator module 6 and the switching power supply module 7, respectively, which simplifies the installation process. The lamp chamber cover hole 9, the power socket hole 10, the main control board hole 11 and the fan hole 12 on the back plate at the rear of the base plate are used to install the lamp chamber cover, the power socket, the main control board and the fan of the spectrophotometer in turn. The lamp chamber cover on the back plate of the instrument can be manually installed and opened, which is convenient for users to replace the lamp source in time when the lamp source life is exhausted. This design can replace the lamp source without disassembling the outer shell, which can greatly reduce the user's operating difficulty and facilitate after-sales personnel and users to maintain the instrument.

[0028] The sample chamber module 4 includes a sample chamber 41 . A first groove 42 is disposed in the sample chamber 41 . A screw hole 43 is disposed in the first groove 42 .

[0029] It should be noted that the groove 42 inside the sample chamber 41 can reduce deformation and warping during the molding process of the sample chamber module, and the screw hole 43 is used to fix the sample rack.

[0030] A threaded insert 12 is provided on the base plate 1 .

[0031] The monochromator module 6 is provided with a second groove 13 and a monochromator fixing hole 19 .

[0032] It should be noted that there are three threaded inserts 12 in the main control board module 5 area for fixing the instrument main control board. Four threaded inserts 12 are provided in the lamp room installation area for fixing the lamp room baffle, which is specially used for ultraviolet spectrophotometer equipment to separate visible light and ultraviolet light.

[0033] The monochromator fixing hole 19 can match an automatic monochromator or a visible light monochromator. The base plate 1 has strong compatibility. The second groove 13 inside the base plate near the monochromator exit light hole can adapt to a circular filter. When a normal filter is used, the second groove 13 is empty. When a circular filter is needed, the circular filter is placed in the second groove 13.

[0034] The switch power module 7 is provided with a sinking space 14 , and the sinking space 14 is provided with screws 15 .

[0035] It should be noted that the sunken space 14 on the side of the instrument is used to accommodate the switching power supply. There are three screws 15 for fixing the switching power supply. The distances between the three screws 15 are different. When in use, any two screws can be selected to adapt to switching power supplies of different specifications.

[0036] The reinforcing rib module 3 includes a first reinforcing rib 31 , and a second reinforcing rib 32 is disposed at the bottom of the first reinforcing rib 31 .

[0037] It should be noted that the criss-crossed reinforcing ribs 31 strengthen the structural strength of the base plate assembly, and the obliquely crossed reinforcing ribs 32 and the longitudinally and transversely arranged reinforcing ribs 31 interact and cooperate with each other, ensuring that the longitudinal and transverse strength of the instrument meets the use requirements while also meeting the diagonal strength requirements.

[0038] The sample chamber module 4 is provided with a rib 16 .

[0039] It should be noted that the rib 16 is used to increase the sealing performance of the sample chamber 41, shielding the external ambient light from entering the sample chamber 41, thereby improving the stray light index of the instrument.

[0040] A circular groove 17 is provided on the bottom plate 1 , and a foot 18 is installed at the bottom of the circular groove 17 .

[0041] It should be noted that the end surface of the machine foot 18 is a circular plane, and a shock-absorbing foot pad can be pasted on this plane to increase the adhesion between the instrument and the work surface, reduce the impact of accidental vibration on the instrument performance indicators during the use of the instrument, and enhance the lateral strength and stability of the instrument.

[0042] During use, since the parts are integrally formed into a mold, the main components of the spectrophotometer, such as the monochromator, power supply, and sample holder, can be directly installed on the spectrophotometer base plate assembly device, and different sample holders can be selected according to different instrument use requirements. In addition, it is compatible with manual monochromators and automatic monochromators, and the lamp chamber cover can be removed to replace the lamp source in time when the lamp source life is exhausted without disassembling the shell.
