Abstract
The observation device includes a front polarizing film and a back polarizing film and a telescope arranged on a straight line of optical axis of telescope. Included angle between the front polarizing film and the back polarizing film is continuous adjustable in range 0-90 degrees. Thus, transmissibility of light ray from hot body is continuous adjustable in range 0-50%. Human eyes are in condition of best observation state so as to raise resolving power and reducing observational error. The observation device is applicable to crystal preparation and metallurgy industries.
Description
Technical field:
The present invention relates to a kind of object observation device, particularly relate to a kind of observation device high temp objects.
Background technology:
At present, for high temp objects or pyroprocess, for example the observation of material crystal growing process adopts naked eyes directly to carry out usually, and in order to reduce high-brightness light that high temp objects sends to the irritating of human eye, the observer wears sunglasses usually and observes.Yet each one vision is also inequality for the sensation of light luminance, even two eyes of same individual are all not necessarily the same for the brightness sensation of same object, so bigger deviation can occur when observing, this point is particularly evident in to the observation of using the Czochralski grown high temperature crystal.Therefore be difficult to make human eye to be adjusted to the optimal viewing state for the crystal of different growth temperatures or the different phase of crystal growth, because crystal growth is the very long process of one-period, the deviation of observing usually causes the observation personnel to take different growth technique measures, thereby make the control of crystal growing process is made a fault, the result influences the quality of crystal.
Summary of the invention:
In order to overcome the shortcoming of prior art, the invention provides a kind of eyes of observation personnel that make and be in the optimal viewing state, improve resolution characteristic, reduce the high temp objects observation device of observational error.
The technical scheme that the present invention takes is, a kind of high temp objects observation device, it is combined by two polarisation systems and telescopic system, polaroid, a rear polarizer and a telescope before including one, polaroid and telescopical optical axial are on same the straight line, and the angle of preceding polaroid and rear polarizer polarization direction is adjustable continuously in 0～90 ° of scope.
The polaroid of high temp objects observation device of the present invention and the setting of telescopical position are risen by the front end near observed object and are followed successively by preceding polaroid, rear polarizer and telescope; The order that above-mentioned position is provided with also can be preceding polaroid, telescope and rear polarizer, perhaps is telescope, preceding polaroid and rear polarizer.
Compared with prior art, the invention has the beneficial effects as follows that using a kind of high temp objects finder has substituted the traditional approach that uses sunglasses observation high temp objects, realized the continuous adjustable control of high temp objects institute isolychn 0～50% transmitance, thereby make human eye be in the optimal viewing state, amplified the observation scene simultaneously, improve resolution characteristic, reduced observational error.

Fig. 1 is a fundamental diagram of the present invention.
Fig. 2 is the concise structure synoptic diagram of the embodiment of the invention 1.
Fig. 3 is the concise structure synoptic diagram of the embodiment of the invention 2.
Fig. 4 is the concise structure synoptic diagram of the embodiment of the invention 3.
Embodiment:
Now with specific embodiment the present invention is specified in conjunction with the accompanying drawings.
Fig. 1 is a fundamental diagram of the present invention, the high light I that high temp objects O is sent
0Mainly comprise two parts, the one, the natural light that self sends, this part is that we observe the needed light of high temp objects O, but when this part light is too strong, can influence of the observation of our eye E for object, so need filter a part to be fit to the observation requirement of eye, a part is the reflected light of high temp objects in addition, and this part light need filter as much as possible based on polarized light.Adjust first polaroid P1 and can significantly reduce catoptrical intensity, make intensity of reflected light reach very low.Like this, will the only remaining linearly polarized photon I identical by first block of later light of polaroid with its polarization direction
1, intensity is about original light I
01/2.The polarization direction of second polaroid P2 becomes angle theta with the polarization direction of first polaroid P1, by the light I after second polaroid P2
2With by before light I
1Luminous flux between following relation: I is arranged
2≈ I
1Cos
2θ, therefore, it is adjustable continuously between 0～50% to regulate the light that the polarization direction angle theta of first polaroid P1 and second polaroid P2 just can make human eye E receive, thereby is adjusted to the observation state of human eye the best.Telescope T makes the observation subtended angle of human eye increase the observed object that " furthered ".
Fig. 2 is the concise structure synoptic diagram of the embodiment of the invention 1.The observation device of high temp objects shown in the figure is combined by two polarisation systems and telescopic system, polaroid 1, rear polarizer 2 and telescope 3 before including, three's optical axial is on same the straight line, the enlargement factor of telescope 3 be 6 times adjustable, the angle of the polarization direction of polaroid 1 and rear polarizer 2 is adjustable continuously in 0～90 ° of scope before above-mentioned, thereby the high temp objects light luminance that the adjusting human eye receives is so that human eye is in the optimal viewing state.In the described high temp objects observation device of present embodiment, the setting of the position of each member is risen by the front end near observed object and is followed successively by preceding polaroid 1, rear polarizer 2 and telescope 3.
The position of each member is provided with the mutual order that also can change them in the high temp objects finder of the present invention, in the embodiment of the invention 2 shown in Figure 3, the setting of the position of each member is risen by the front end near observed object and is followed successively by preceding polaroid 1, telescope 3 and rear polarizer 2; In embodiment shown in Figure 43, its position setting is risen by the front end near observed object and is followed successively by telescope 3, preceding polaroid 1 and rear polarizer 2.
High temp objects observation device of the present invention has been realized the continuous adjustable control to high temp objects institute isolychn 0～50% transmitance, make human eye be in the optimal viewing state, improve resolution simultaneously, reduced observational error, can be widely used in industries such as crystal preparation and metallurgy.
