Embodiment 1

[0023] Example 1 as figure 1 Shown, a kind of spectrometer based on CCD imaging comprises a telescope 1, a stage 2, and a support 5 is installed on the eyepiece 4 of the telescope, and the structure of the support 5 is as follows figure 2 As shown, the CCD element 6 is installed in the bracket 5 and connected with the eyepiece 4 of the telescope. The CCD element is connected to the display screen through a data line. The image in the telescope is presented on the display screen through the CCD element. A small level 3 is installed above the objective lens of the telescope 1 . A level is also installed on the table top of the stage 2, and the shape and size of the level are the same as the table top of the object stage.

[0024] The telescope of the spectrometer is a telescope with an Abbe eyepiece, which consists of three parts: the eyepiece, the objective lens, and the reticle. A 45° total reflection Abbe prism is attached to the bottom of the reticle, and its surface is...

Embodiment 2

[0026] Embodiment 2 A kind of adjusting method based on the spectrometer of CCD imaging, this method comprises the following steps: 1, coarse adjustment level

[0027] (1) Adjust the screws of the stage, telescope, etc., so that they are in the middle state of free movement, lock the stage, loosen the stop screw of the vernier plate, loosen the stop screw of the telescope, and turn the scale line "0" After adjusting to the bottom of the telescope, tighten the linkage screw between the dial and the telescope;

[0028] (2) According to the position of the telescope and the level on the stage, adjust the vertical adjustment screws of the collimator and the telescope so that the level is in the center; then adjust the two adjustable screws under the stage to make the table The upper level is in the central position. After rough adjustment, the collimator, telescope, and stage surface are roughly horizontal, so they are roughly perpendicular to the main axis of the spectrometer.

Abstract

The invention discloses an optical experiment instrument, in particular to a spectrometer based on CCD imaging and an adjusting method thereof. The spectrometer based on the CCD imaging includes a telescope, wherein an eyepiece of the telescope is connected with a CCD component. An adjusting method provided by the invention comprises the following steps: 1, roughly adjusting the level; 2, finely adjusting the level; 3, adjusting an objective table platform to be perpendicular to a spectrometer principal axis. The spectrometer based on the CCD imaging and the adjusting method thereof have the advantages that a CCD imaging principle is utilized to present images within the view of the telescope of the spectrometer on a display screen clearly, so that the observation vision field is enlarged greatly, the visual fatigue is reduced and the observation and measurement of experiment are facilitated; and besides, a leveling instrument is added on each of the objective table and a telescope lens cone, so that the precision of rough adjustment is improved greatly and the difficulty of adjustment is further lowered; in the adjusting method, three adjusting screws adopt the method of one fixing and two adjusting, so that the operating difficulty of the experiment is lowered greatly and the adjusting experiment is simpler and more convenient and easy to operate.

Description

technical field [0001] The invention relates to an optical experiment instrument, in particular to a spectrometer based on CCD imaging and an adjustment method thereof. Background technique [0002] A spectrometer is a precision instrument for measuring angles. The basic principle is to let the light pass through the slit and the focusing lens to form a beam of parallel light, which enters the telescope objective lens after being reflected or refracted by the optical element and is imaged on the focal plane of the telescope, then observe and measure the deflection of various light rays through the eyepiece Angle, so as to obtain optical parameters such as refractive index, wavelength, dispersion rate, diffraction angle, etc. Familiarity with the basic structure, adjustment principles, methods and techniques of the spectrometer is of general guiding significance for the adjustment and use of other optical instruments. And the spectrometer is a very important optical instrum...
