Description
(1) technical field
The utility model relates to a kind of optical instrument, particularly a kind of spectrometer.
(2) background technology
Spectrometer is a kind of optical instrument that can accurately take measurement of an angle.The student as reflection angle, refraction angle, angle of diffraction or the like, reaches many optical quantities (as optical wavelength, refractive index, grating constant etc.) through this Instrument measuring light deflection angle commonly used.The spectrometer adjustment requires:
1. telescope focuses on directional light, and its optical axis is vertical with the spectrometer central shaft.
2. the objective table plane is vertical with the spectrometer central shaft.
Adjustment process is very loaded down with trivial details, especially pass through the objective table levelling bolt to the objective table table-surface level, and telescope optic axis height set screw is to the adjusting of telescopical luffing angle, taken its most of the time especially, the student does not have experience generally can take much time to be used for debug process, cause and to practise fully other steps, lost the meaning of course offered.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, provide a kind of simple in structure, debug spectrometer easily.
The utility model is achieved by the following technical solution:
A kind of spectrometer comprises the spectrometer body, and telescope, objective table are set respectively on the spectrometer body, and its special character is: between telescope, objective table and the spectrometer body stepper motor is installed respectively.
Between the support arm of described telescopical rear portion and spectrometer body stepper motor is set, three stepper motors of following even distribution of objective table, this stepper motor is positioned at the top of the brake bracket of spectrometer body, regulates the level of telescopical luffing angle and objective table table top by stepper motor.
Described stepper motor comprises step actuator and adaptive with it control system, this control system comprises Crossed Circle pulse signal system, power driving circuit, when step actuator receives the pulse signal that a Crossed Circle pulse signal system sends, it rotates a fixing angle with regard to drive stepping motor by the direction of setting, be called " step angle ", its rotation is to move step by step with fixing angle.
The beneficial effects of the utility model are: the angular displacement of stepper motor or displacement of the lines are controllable, can come the pilot angle displacement by the gating pulse number, thereby reach the purpose of accurate location, be convenient to the adjusting of objective table table-surface level and telescopical luffing angle, simple to operate, save time, and satisfy requirement simple in structure.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is a structural representation of the present utility model;
Among the figure, 1 spectrometer, 2 telescopes, 3 objective tables, 4 stepper motors, 5 support arms, 6 brake brackets.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises spectrometer body 1, and telescope 2, objective table 3 are set respectively on the spectrometer body 1, between telescope 2, objective table 3 and the spectrometer body 1 stepper motor 4 is installed respectively.The place that the close eyepiece of stepper motor 4(is set between the support arm 5 of the rear portion of described telescope 2 and spectrometer body 1 is the back), three stepper motors 4 of following even distribution of objective table 3, this stepper motor 4 is positioned at the top of the brake bracket 6 of spectrometer body 1, regulates the luffing angle of telescope 2 and the level of objective table 3 table tops by stepper motor 4.Described stepper motor 4 comprises step actuator and adaptive with it control system, this control system comprises Crossed Circle pulse signal system, power driving circuit, when step actuator receives the pulse signal that a Crossed Circle pulse signal system sends, it rotates by the direction of setting with regard to drive stepping motor.
Wherein stepper motor 4 is that first stepper motor spare is controlled in the open loop that electric impulse signal changes angular displacement or displacement of the lines into.Under the situation of non-overload, the frequency and the umber of pulse of pulse signal only depended in rotating speed of motor, the position that stops, and be not subjected to the influence of load variations, when step actuator receives a pulse signal, it rotates a fixing angle with regard to drive stepping motor by the direction of setting, be called " step angle ", its rotation is to move step by step with fixing angle.Can come the pilot angle displacement by the gating pulse number, thereby reach the purpose of accurate location; Can control speed and the acceleration that motor rotates by the gating pulse frequency simultaneously, thereby reach the purpose of speed governing.It must can be used by forming control systems such as Crossed Circle pulse signal, power driving circuits.
Usually the rotor of stepper motor 4 is a permanent magnet, and when electric current flow through stator winding, stator winding produced a Vector Magnetic Field.This magnetic field can drive rotor and rotate an angle, makes that the pair of magnetic field direction of rotor is consistent with the magnetic direction of stator.Angle of Vector Magnetic Field rotation when stator.Rotor is also along with an angle is changeed in this magnetic field.Electric pulse of every input, motor rotates an angle and takes a step forward.The angular displacement of its output is directly proportional with the umber of pulse of input, rotating speed is directly proportional with pulsed frequency.Change the order of winding energising, motor will reverse.So rotation that the power-up sequence of available gating pulse quantity, frequency and each phase winding of motor is come the control step motor.
