It shares many of the exceptional properties of standard CAP, such as excellent chemical resistance and low birefringence
These films exhibit partial relaxation followed by rapid increase in birefringence
due to the accelerating effect of orientation on crystallization.
Service is typically performed to validate orientation when thermal-expansion, -coefficient, and the index of refraction needs to be constant in all directions, and when birefringence
must be minimum or maximum, and polarization effects are critical
PLEXIGLAS and PLEXIMID molding compounds are especially suited for lenses in LED headlamps Product benefits: no optical birefringence
effects with PLEXIGLAS, highest possible transparency and negligible drop in light transmission even after years of service.
Through the examination of many other contractile structures in various organisms, such as the body wall of Hydra, the contractile stalk of vorticellids and other ciliates, contractile protoplasm, and embryonic muscle cells, Engelmann concluded that wherever and in whatever form it may occur, contractility was linked to the presence of birefringence
The industry has developed different types of films with improved optical properties, specifically without birefringence
(the effect of which becomes visible in polarized light): Cyclic Olefin Polymer (COP) and Cellulose Triacetate (TAC).
2] Amyloidosis, either primary or secondary, is defined as a group of chronic infiltrative disorders that have in common a beta-pleated sheet configuration visualized on X-ray diffraction, a fine fibrillar nonbranching appearance on electron microscopy, and an apple-green birefringence
when examined under polarized light after staining with Congo red.
They cover properties of liquid crystals, polarization and birefringence
in liquid crystal devices, liquid crystal displays, spatial light modulators, spatial light modulators as optimal elements, adaptive optics with liquid crystals, and looking ahead at liquid crystal devices.
With standard gemmological testing, the material is easily recognizable by its strong carbonate birefringence
blink on the refractometer.
Tokyo, July 2, 2014 - (JCN) - Asahi Kasei Chemicals has developed AZP(TM), a new optical polymer featuring zero birefringence
, achieved through novel molecular design.
He covers the nuclear optics of polarized matter, nuclear pseudomagnetism, "optical" spin rotation and the birefringence
effect of high-energy particles, and channeling and high-energy nuclear optics in crystals.
The system has a motorized X-Y stage with joystick controls to navigate, observe, and measure bonded wafer/die alignments; find defects in a manual mode; and determine material stress via the system's optional birefringence
