Abstract
The invention discloses a surface stress measuring device. The surface stress measuring device comprises a light source, a prism, a reflector, a telescope system and a micrometer eyepiece. The light source, the prism and the reflector are arranged above a tested sample side by side. A baffle provided with a slit is arranged between the light source and the prism. Light emitted by the light source irradiates the prism through the slit, refraction is conducted on the light through the prism, so that the light irradiates the tested sample, the light is reflected to the reflector, and the light reflected by the reflector enters the micrometer eyepiece through the telescope system. The surface stress measuring device is high in precision, small in measurement error, simple in structure, convenient to install and measure, low in manufacturing cost, convenient to use, practical and wide in application range.
Description
Technical field
The present invention relates to a kind of stress measurement device, particularly a kind of stress measurement device being applied to glass surface.
Background technology
Due to the singularity of production technology, in the glassware after completing, also there is internal stress more or less.In glass forming process, due to external mechanical force effect or cooling time heat uneven produced stress be called thermal stress or macro-stress.At inside glass, the stress that the micro-uneven district formed due to uneven components causes is called structural stress or microstress.Stress existing in the volume range being equivalent to unit cell dimension in glass is called ultramicroscopic view stress.Due to the architectural characteristic of glass, microcosmic wherein and ultramicroscopic view stress minimum, little on the impact of the physical strength of glass.What have the greatest impact is thermal stress in glass, because this stress is normally extremely uneven, can reduces physical strength and the thermal stability of glassware, affect the safe handling of goods, even autoclasis phenomenon can occur time serious.Therefore, in order to ensure safety when using, various glassware is all specified that the internal stress of its remnants can not exceed a certain setting.For optical glass, the existence of larger stress will have a strong impact on light transmission and image quality.Therefore, the internal stress measuring glass is a kind of means of Mass Control, particularly the product of the valuable or precision that quality requirements is higher is even more important, take place frequently due to earthquake disaster, the glazing in urban high buildings and large mansions, apartment all can use safety glass, do not have clear and definite specification about safety glass for building, former analyzer sensitivity is very low, is difficult to carry out sufficient qualitative control.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of structure simple, measuring accuracy height surface stress measurement device.
The present invention in order to the technical scheme solving its technical matters and adopt is: a kind of surface stress measurement device, comprise light source, prism, reflective mirror, telescopic system and micrometer eyepiece, described light source, prism and reflective mirror are located at above tested sample side by side, the baffle plate that one has slit is provided with between described light source and prism, the light of described light source injection is irradiated on prism through slit, find on tested sample through prismatic refraction, and reflex to reflective mirror, enter micrometer eyepiece by the light after mirror reflection through telescopic system.
As a further improvement on the present invention, analyzing prism and graticule is provided with between described telescopic system and micrometer eyepiece.
As a further improvement on the present invention, an interference filter is also provided with between described telescopic system and reflective mirror.
The invention has the beneficial effects as follows: glass surface of the present invention answers power apparatus precision high, and error during measurement is little, and apparatus of the present invention structure is simple, install and measure conveniently, cost of manufacture is cheap, easy to use, and applicability is wide.
