Description
Technical field
The utility model relates to optical fields, fill more particularly, to a kind of auxiliary for the adjustment of spectroscope original state
It sets.
Background technique
Spectroscope is a kind of common optical instrument of deflection angle between precise measurement incident light and emergent light.Spectroscope tune
Whole principle, method and skill, have certain representative in optical instrument, and it is common to be that engineering and polytechnic universities, university, China student must do
One of Physical Experiment.
The difficult point and key of entire spectroscope adjustment are coarse adjustment states.Way general at present is that user uses range estimation side
It is parallel with objective table to adjust telescope optic axis for method.The range of telescope of spectroscope is small, only 3 ° or so of visual angle, accurate due to lacking
Target, the student of first contacts spectroscope are difficult with ocular estimate, completion coarse adjustment.In experiment, rotation is placed with the load of plane mirror
When object platform, student does not usually see " the cross picture " of reflection, or is only capable of seeing " the cross picture " of reflection on one side in plane mirror.Very
Even if coarse adjustment effect is preferable when more, because adjustment amplitude and direction are improper when fine tuning, and it will lead to reflection " cross picture " and lose,
Coarse adjustment must be re-started.It is ignorant to will lead to student in this way, attend class teacher 2 class hour finite time, face tens beginners
Can feel unable to do what one wishes, every class all can some student cause not can be carried out subsequent light splitting since spectroscope coarse adjustment is unsuccessful
The further adjustment and measurement of instrument.A kind of small utility device for the adjustment of spectroscope original state that we develop, can be with
It allows student intuitively fast and accurately to complete the coarse adjustment of spectroscope, it is puzzled to solve beginner's coarse adjustment.
Physics notification 2008 (8) phase page 57 discloses the text of the tips for the quick coarse adjustment spectrometer that Yang Defu is delivered
Chapter, it is contour as far as possible that adjusting method disclosed in this article adjusts three screws under article carrying platform first, and adjusts under telescope
Inclination angle screw to make telescope optic axis parallel with loading table top as far as possible, if telescope still cannot see that by small after having done so
Plane mirror is reflected green " cross picture ", then can be small from the orientation of telescope is with eyes directly from telescope side
Plane mirror (does not pass through sem observation of looking in the distance), at this point, rotate objective table on one side, is on one side reflected back the eyes searching that moves up and down
Green " the cross picture " come, since eyes can be searched in biggish field range, it is easier to find reflected green
" cross picture " is then adjusted the center for arriving small flat mirror by " cross picture ", at this time again by sem observation of looking in the distance it can be seen that by small flat
Face mirror is reflected green " cross picture ".However this method depends on operator, still proposes to user higher
Requirement.It is not suitable for the teaching to beginner.
