Birefringence Measurement Of Large-Format Samples
US Patent:
6992758, Jan 31, 2006
Filed:
Feb 5, 2003
Appl. No.:
10/359529
Inventors:
Andrew D. Kaplan - Portland OR, US James C. Mansfield - Hillsboro OR, US Douglas C. Mark - Tigard OR, US
Assignee:
Hinds Instruments, INC - Hillsboro OR
International Classification:
G01N 21/01
US Classification:
356244, 356365
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.
