  • Polarization Standards for Microscopy
    Publication number: 20110089317
    Abstract: The present invention describes the development of thin film calibration strips for microscopy/spectroscopy systems and a simple method/routine to conduct instrument calibration using partially (uniaxially) oriented strip to calibrate microscopy system without the prior knowledge of exact polarization of the strip. The invention describes results from studies including a styryl derivative (LDS 798) embedded in poly(vinyl alcohol) (PVA) film. These films were progressively stretched up to 8 folds. Vertical and horizontal components of absorptions and fluorescence were measured and dichroic ratios were determined for different film stretching ratios. The stretched films have high polarization values for isotropic excitation. The isotropic and stretched PVA films doped with LDS 798 can be used as etalons in near infra red (NIR) spectroscopic measurements.
