Descrizione :

Hinds Instruments Birefringence Measurement technology has been adopted by industry leaders world wide to measure birefringence and characterize stress birefringence in materials with unsurpassed accuracy, resolution and repeatability. Exicor 150AT measures retardation integrated along an optical path through the optical sample under investigation. It is designed to measure and display both the magnitude and fast axis orientation of the samples optical retardation. The bench top design and intuitive automated scanning software make this product the best choice for day-in-day-out evaluation of both High Value precision optical components and Commodity optics up to 150mm X 150mm.

The Exicor 250AT incorporates a larger scan area (up to 250mm x 250mm) while maintaining the desk top nature of the Exicor 150AT system.
