Problems solved by technology

However, the vision of each person has different perceptions of the brightness of light, and even the two eyes of the same person may not have the same perception of the brightness of the same object, so there will be a large deviation when observing. This is especially evident in observations of high temperature crystals grown by
Therefore, it is difficult for the human eye to adjust to the best observation state for crystals with different growth temperatures or different stages of crystal growth. Since crystal growth is a long-term process, observation deviations often lead observers to adopt different growth process measures. As a result, the control of the crystal growth process is wrong, and the quality of the crystal is affected as a result.

Embodiment Construction

[0011] The present invention will now be described in detail in conjunction with the accompanying drawings and specific embodiments.

[0012] figure 1 It is the working principle diagram of the present invention, the strong light I emitted by the high-temperature object O 0 It mainly includes two parts, one is the natural light emitted by itself, this part is the light we need to observe the high-temperature object O, but when this part of the light is too strong, it will affect our eyes E's observation of the object, so we need to filter out part of it to fit The observation requirements of the human eye, another part is the reflected light of high-temperature objects. This part of the light is mainly polarized light, which needs to be filtered out as much as possible. Adjusting the first polarizer P1 can greatly reduce the intensity of reflected light, so that the intensity of reflected light can be very low. In this way, the light after passing through the first polarizer...

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: [0001] The invention relates to an object observation device, in particular to an observation device for high-temperature objects. Background technique: [0002] At present, the observation of high-temperature objects or high-temperature processes, such as the growth process of material crystals, is usually carried out directly with the naked eye. In order to reduce the stimulation of the high-brightness light emitted by high-temperature objects to human eyes, observers usually wear sunglasses for observation. However, the vision of each person has different perceptions of the brightness of light, and even the two eyes of the same person may not have the same perception of the brightness of the same object, so there will be a large deviation when observing. This is especially evident in observations of high-temperature crystals grown by the method. Therefore, it is difficult for the human eye to adjust to the best observation state for crystals with differe...
