  • Birefringence measurement of large-format samples
    Patent number: 6992758
    Abstract: The disclosure is directed to systems and methods for precisely measuring birefringence properties of large-format samples of optical elements. A gantry-like configuration is employed for precise movement of birefringence measurement system components relative to the sample. There is also provided an effective large-format sample holder that adequately supports the sample to prevent induced birefringence therein while still presenting a large area of the sample to the unhindered passage of light.
    Type: Grant
    Filed: February 5, 2003
    Date of Patent: January 31, 2006
    Assignee: Hinds Instruments, INC
    Inventors: Andrew D. Kaplan, James C. Mansfield, Douglas C. Mark
