Polariscope for Glass 

A Polariscope for Glass is a highly precise optical device designed to detect, analyze, and measure internal stresses or strains in transparent materials such as glass, plastics, and crystals. In the glass manufacturing and processing industry, controlling internal stress is crucial to ensure product quality, durability, and safety. The polariscope makes this possible by using polarized light to reveal invisible stress patterns inside the glass.

 

How It Works

The Polariscope for Glass operates on the principle of polarized light. When light passes through a strained glass sample, it gets refracted differently due to stress variations. These variations appear as colorful or dark patterns when viewed through the polariscope, helping engineers and quality control experts to evaluate the material’s structural integrity.

Applications

  • Glass container and bottle manufacturing
  • Toughened and tempered glass quality checks
  • Optical component inspection
  • Research laboratories and educational institutions
  • Plastic and crystal stress analysis

Benefits

  • Detects internal stress before defects occur
  • Improves product safety and durability
  • Ensures compliance with international quality standards
  • Saves time and reduces production losses
  • ideal for routine quality control and research

Melt Flow Index Tester - NEO 2.0

Sri Lanka's plastic and polymer industry is heavily dependent on good-quality materials. The absence of a melt flow index instrument does not allow for consistency, flowability, or good-quality raw materials coming into the manufacturer's production floor. Inconsistencies in melt flow often lead to defective products, wasted materials, and inefficiencies in production. The result will be poor product performance, loss of customer satisfaction, and a competitive advantage globally.
