Abstract
The invention provides a temperature control polarimeter which mainly comprises a light source, two Nicol prisms, a polarization tube groove, a polarization tube and a controller. The inner wall of the polarization tube groove is provided with a temperature sensor, a plurality of electronic refrigerating chips are distributed uniformly at the periphery of the polarization tube groove, the hot surfaces of the upper and the lower electronic refrigerating chips face the outside of the polarization tube groove, and the upper surface of the polarization tube groove is provided with exhaust fan holes in a covering way, the hot surfaces of the front and the back electronic refrigerating chips face the inside of the polarization tube groove, and electronic refrigerating chip circuits are respectively connected with a temperature relay. After a temperature is set by the controller, when the room temperature is higher than a testing temperature, the upper and the lower electronic refrigerating chips are opened so as to start refrigerating, heat is dissipated by the exhaust fan, when the set temperature is reached, the temperature relay cuts off a refrigerating circuit, when the room temperature is lower, the front and the back electronic refrigerating chips are opened so as to start heating, and when the set temperature is reached, the temperature relay cuts off a heating circuit. The temperature control polarimeter has the following beneficial effect: the temperature relay is used to control a constant temperature circuit of the polarimeter, thus acquiring accurate testing result.
Description
Technical field
The present invention relates to a kind of polarimeter, especially a kind of temperature control polarimeter.
Background technology
As everyone knows, visible light is that a kind of wavelength is the electromagnetic wave of 380nm ~ 780nm, because the luminous statistical property of luminophor, the direction of vibration of electromagnetic electric vector can be got perpendicular to the arbitrary orientation on the optical propagation direction, is called natural light usually.Utilize some device (for example polarizer) that direction of vibration is fixed on a certain orientation perpendicular to the light wave propagation direction, form so-called linearly polarized light, when linearly polarized light passes through certain material, the direction of vibration of polarized light can turn over an angle, this material is called optical active substance, and the angle that polarized light turned over is optical activity.If linearly polarized light is by certain pure optical active substance, the size of optical activity is relevant with following three factors:
A) wavelength X of linearly polarized light, the different optical activities of wavelength are different.
B) temperature t of optical active substance, different temperature optical activities is different.
C) kind of optical active substance, different optical active substances has different optical activities.
But, the polarimeter of present most of manufacturer production all is comparatively old-fashioned WZZ type polarimeter, it is automatic polarimeter, though it is comparatively convenient during reading, but have no idea to solve the problem of temperature variation, read repeatedly to average even the tester connects, still have very mistake for the responsive to temperature type material.
Summary of the invention
At the problems referred to above, the invention provides a kind of temperature control polarimeter.
A kind of temperature control polarimeter, mainly by a light source, two Nicols, the optically-active tube seat, polarization tube and controller are formed, it is characterized in that optically-active tube seat inwall is provided with a temperature inductor, around the optically-active tube seat, be evenly distributed with a plurality of electronic cooling sheets, the hot side of upper and lower surface electronic cooling sheet is outside the optically-active tube seat, optically-active tube seat upper cover is provided with the exhaust fan hole, dull thread passes through between itself and the optically-active tube seat, the hot side of the electronic cooling sheet on two sides, front and back is in the optically-active tube seat, each is connected the electronic cooling sheet circuit of heating and refrigeration with a temperature relay, after via controller configures temperature, when room temperature is higher than probe temperature, opens electronic cooling sheet up and down and begin refrigeration, and dispel the heat by exhaust fan, when reaching design temperature, temperature relay disconnects refrigeration circuit, and when low as if room temperature, the electronic cooling sheet of opening front-back begins heating, when reaching design temperature, temperature relay disconnects heater circuit.
Remarkable result of the present invention is the constant-temperature circuit that utilizes temperature relay control polarimeter, not only can control temperature in the polarimeter at any time, and the power of electronic cooling sheet is less, than being easier to keep constant temperature, the accurate test result of easier acquisition.
