Description
Technical Field
The utility model relates to a quick leveling type spectrometer with adjustable physics optics experimental apparatus field, especially base.
Background
Spectrometers are commonly used instruments in college physics experiments. Azimuthal observation and measurement can be performed with a spectrometer. The spectrometer adjustment steps are extremely complicated and are mainly classified into two steps of coarse visual adjustment and fine optical adjustment. The accuracy of the coarse adjustment by visual inspection directly determines the efficiency of the subsequent optical fine adjustment. Visual fine-tuning is too dependent on experiential experience and experimental techniques, making it difficult for many primary experimenters to make accurate adjustments.
In order to reduce the difficulty of coarse tuning of spectrometers on the visual scale, several types of improved spectrometers have been devised on the market. The main design idea is to arrange gradienters on an objective table, a telescope and a collimator of a spectrometer, and help experimenters to quickly carry out rough adjustment by means of visual display of the gradienters. The spectrometer model that is commonly used is the HAD-JJY1 spectrometer, which has the following two defects, and the utility model improves the spectrometer model. (1) The level of the spectrometer mount is ignored. The reading of the spectrometer angle requires that the four planes be horizontal to each other. These four planes are: the plane of the telescope, the plane of the collimator, the plane of the object stage and the plane of the dial. Since the dial is parallel to the spectrometer mount, if the spectrometer mount is not level, the dial plane is also not level. When the table on which the spectrometer is placed is not flat, the adjustment error is still large even if the telescope, the collimator and the objective table are all adjusted to be horizontal. (2) The level gauge is ignored for service, maintenance and zero calibration. According to the existing design scheme, the gradienter is mostly embedded. The level needs to be checked and calibrated again after long-term use, and also needs to be corrected for zero. Even for coarse adjustment, if the level gauge is used for a long time without performing zero calibration, a large adjustment error is caused. The level meter embedded in the spectrometer cannot be subjected to zero calibration in the current design.
