1. an optical instrument used to examine the polarization properties of light or to detect stress in transparent materials
Usage: technical; optics

Examples

• The engineer used a polariscope to detect internal stress in the glass component.
• Scientists employed a polariscope to study the optical properties of the crystal.
• The polariscope revealed strain patterns invisible to the naked eye.
• Quality control technicians rely on polariscopes to inspect plastic parts for defects.
• The laboratory’s polariscope helped researchers analyze the molecular structure of the polymer.
• Using a polariscope, the geologist examined the mineral’s optical characteristics.
