Background

A spectrophotometer, also called a spectrometer (spectrometer), is a scientific instrument that decomposes light with complex components into spectral lines. The measurement range generally comprises a visible light region with a wavelength range of 380-780 nm and an ultraviolet light region with a wavelength range of 200-380 nm. Different light sources have their own emission spectra, so that different illuminants can be used as the light source for the instrument. The emission spectrum of the tungsten lamp is that the spectrum light with the wavelength of 380-780 nm emitted by a tungsten lamp light source is refracted by a prism to obtain a continuous chromatogram consisting of red, orange, yellow, green, blue, indigo and purple; the color spectrum can be used as a light source of a visible spectrophotometer.

Detailed Description

The following will combine the drawings of the embodiments of the present invention to further describe the technical solution of the present invention, and the present invention is not limited to the following specific embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

As shown in fig. 1 to 4, a multi-angle jig for spectrum test of a spectrophotometer includes: base 100 and pointer piece 200, be provided with calibrated scale 300 in the one side of base 100, be provided with a plurality of scale 310 on the calibrated scale 300, it is a plurality of scale 310 equidistance sets up, base 100 is provided with two locating holes 101 have been seted up in the one side of calibrated scale 300, two locating hole 101 corresponds to be seted up, mounting hole 102 has still been seted up on the base 100, mounting hole 102 is located the center of calibrated scale 300, pointer piece 200 includes connecting block 210 and two pointers 220, the one end of connecting block 210 sets up one pointer 220, the other end sets up another pointer 220, a side of connecting block 210 through a connecting piece with mounting hole 102 swing joint.
