In addition, the Bayfol HX material was also used for astronomical Volume Phase
Holographic Gratings (VPHGs).
The NIPAM component in the poly(NIPAM-VAA-AAm) microgels network undergoes a volume phase
transition from swollen to shrunken (collapsed) state with increasing temperature.
That volume phase
of the mining boom certainly hasn't ended yet.
The core differentiator is the use of P&P Optica's high-efficiency, transmission-based Volume Phase
Holographic (VPH) gratings, which provide average absolute diffraction efficiency greater than 75%, far more than the typical 35% of ruled and holographic gratings, and a signal-to-noise ratio of 100,000:1.
The series employs a Volume Phase
Grating (VPG) as the spectral dispersion element and an InGaAs array detector as the detection element.
These calculations were made measuring the final salt concentration by conductimetry and the final external volume phase
(W2), and performing a mass balance of the salt.
Variation in size and volume phase
transition temperature (VPTT) by the introduction of silver nanoparticles in microgels was also investigated.
They then go on to acknowledge that their primary concern in the book is volume phase
holography, which means that other actual or potential ultra-realistic imaging techniques are ignored or only referenced in passing.
The spectrometer integrates multiple volume phase
gratings customized for each specific wavelength region and deep-cooled InGaAs array detectors, providing maximized light throughput.
In consequence, the interfacial tension decreases and the rubber volume phase
is lower (Table 2).
The biggest time savings in the product life cycle can be achieved in the ramp-up to volume phase
between design and full production.
Wasatch Photonics has been exclusively assigned US Patent 6750995 titled Enhanced volume phase
grating with high dispersion, high diffraction efficiency and low polarization sensitivity, recently issued to Dr LeRoy Dickson, one of the company's founders.
