Precautions for use of original FSM-6000LE stress gauge

The original FSM-6000LE stress gauge is surface Stress meter It is a common and commonly used one in. The measuring principle of the surface stress instrument is to use the optical waveguide effect of the ion exchange layer on the glass surface to measure. The diverging light from the light source passes through the slit, converges by the high refractive index cylindrical prism and becomes a parallel light. By adjusting the position of the light source, a beam of parallel light can be incident to the interface between the glass and the prism at a critical angle. Due to the stress on the glass surface, the light is decomposed into vector light with two vibration surfaces perpendicular to each other, These two beams of light propagate at different speeds in the ion exchange layer of the glass, so they are refracted to the prism at different total reflection angles. The light emitted from the prism is reflected by the reflector into the interference filter, focused by the telescope system, and then imaged on the reticle after passing through the analyzer to form a light and dark step image. The analysis software can accurately measure the height of steps and the number of step lines to calculate the surface stress intensity and the depth of stress layer.

1. Please use the original supporting consumables (that is, ORIHARA's original model is GS-1's 1.64 refractive index refractive liquid) to avoid damage to the prism.
2. Please handle the tested sample gently when operating the machine to avoid damage to the prism; When the detection image is not clearly displayed, please use a cotton swab stick dipped in industrial alcohol to gently wipe the prism surface and bevel.
3. When using this machine, it is necessary to avoid connecting to the Internet and LAN, as well as floppy disks or hard disks with virus USB interfaces.
4. Please use the machine indoors to avoid strong light. The indoor air should not be too humid and the pH should be moderate. 5. Please keep away from other chemicals.
6. In case of any abnormality during use, please contact the relevant supplier immediately to solve it.
7. Please keep the original factory manual and relevant factory report documents.
8. Please replace the consumable "NA/10 sodium lamp" with a new one after the service life of the machine.
9. Please be sure to keep the password dog provided by the original manufacturer of this machine, and be responsible for any loss.
10. Please correctly operate the computer configuration of the machine, and do not force the machine to shut down at will to avoid computer damage.

 
surface Stress meter It is an instrument used to check the size and distribution of stress in transparent objects. It is not only widely used in optical glass, optical instruments, glass products, plastic products and other industries, but also plays an important role in the inspection of safety explosion-proof indicators of building materials, lamps, pharmaceuticals, beverages, handicrafts, and also has many applications in the fields of crystal jewelry production, geology and minerals, and materials science. At the same time, the surface stress instrument provided by Dongyi Seiko is also an ideal teaching experimental equipment for colleges and universities.
