The Polariscope Strain Viewer – NXG represents a new generation of optical strain analysis, engineered to deliver unmatched clarity, precision, and ease of use for evaluating internal stresses in transparent materials. Developed for modern quality control and research environments, the NXG brings together advanced polarized-light technology, high-intensity illumination, and ergonomic design to provide users with a superior strain-viewing experience.
The Polariscope Strain Viewer – NXG is an advanced optical inspection device designed to reveal internal stresses and birefringence patterns in transparent materials. Built with next-generation polarized light technology, the NXG allows users to quickly identify strain distribution in glass, plastics, lenses, and molded components. Its high-clarity illumination, ergonomic design, and precision optics make it an essential tool for quality control, research, and manufacturing environments where material integrity is critical.
The Polariscope Strain Viewer – NXG works by passing polarized light through a transparent specimen placed between its viewing plates. When internal stress is present, the material alters the polarization of the light, creating colorful fringe patterns or distinct dark-and-bright zones.
These interference patterns are then viewed through the NXG’s analyzer, helping inspectors instantly visualize stress levels and distribution. With stable LED illumination and fine adjustment controls, the NXG ensures high sensitivity and accurate results for both qualitative and comparative strain analysis.
Accurate Stress Detection: Precisely identifies internal strain, ensuring reliable quality control.
