Spectrometer angular accuracy depends on the adjustment accuracy of spectrometer.Telescope optic axis debugging is led to perpendicular to rotation
Axis, objective table table top debugging to level are two key requests that spectrometer is debugged.As shown in Figure 1, the first step is by double-sided reflecting
The vertical objective table levelling bolt one of mirror mirror surface, two line of objective table levelling bolt are placed, and objective table levelling bolt one, loading are adjusted
Platform levelling bolt two or telescope make telescope optic axis perpendicular to live spindle, while objective table table top using Both-half Adjusting Method
Level is also brought in objective table levelling bolt one, two line direction of objective table levelling bolt.Second step rotates objective table
90 °, double mirror mirror surface is parallel to objective table levelling bolt one, two line of objective table levelling bolt is placed, adjusting loading
Platform levelling bolt three, make objective table table top objective table levelling bolt one, two line of objective table levelling bolt orthogonal direction on
It is adjusted to level.So far, entire objective table table-surface level.
But in practical adjustments, complete to be frequently found after the above two steps operation telescope optic axis and live spindle and non-critical
Vertically, objective table table top is not severity yet.The documents and materials of existing spectrometer also there are no the analysis about this, inquire into and
Counter-measure.
It is found by analysis, is that the placement error of double mirror position in first step operation results in final adjusting mistake
Difference.It is located on the perpendicular bisector of objective table levelling bolt one, objective table levelling bolt two due to objective table levelling bolt three, is carried
The adjusting of object platform levelling bolt three will not change objective table table top that the first step has mixed up in objective table levelling bolt one, loading
Posture on two line of platform levelling bolt.But if double mirror is not exact vertical objective table leveling spiral shell in first step operation
One, two line of objective table levelling bolt are followed closely, although on the new direction mirror normal n1, by adjusting objective table levelling bolt
One, objective table levelling bolt two can also make objective table table-surface level, and telescope optic axis is perpendicular to live spindle.But passing through
After second step operation, due to the mirror normal direction of the no longer vertical first step of perpendicular bisector where objective table levelling bolt three
N1, the adjusting of objective table levelling bolt three will destroy the adjusted result in the direction normal n1 of the first step, and which results in above
It mentions, after completing the operation of two steps, is frequently found telescope optic axis and live spindle is not exact vertical, objective table table top is also simultaneously
Such a result of non-critical level.And this result can not gradually be disappeared by iterating the operation of this two step
It removes.Only in the first step operates, double mirror mirror surface exact vertical objective table levelling bolt one, objective table levelling bolt
When two lines are placed, just objective table table top can be made to be adjusted to level by the operation of this two step, even if the double mirror of second step is deposited
In location error and in this way, because the adjusting on two nonopiate directions can also level objective table table top.Therefore, first
The placement precision of double mirror position is to influence a critically important factor of Spectromenter Adjustment precision in step operation.
However, part spectrometer objective table table top only has concentric loop mark on the market, double mirror position is positioned
Do not have directive significance.Another part spectrometer objective table table top has been superimposed the trilete rays mark for crossing the center of circle in concentric loop mark
Know, does not also have specific directive significance to the positioning of double mirror position.In addition, objective table table top has rotation with respect to levelling bolt
Turn freedom degree, this makes objective table table top be not suitable as that the datum level of positioning identifier is arranged.
