28 Feb 2006 PRG supplies holographic plates for the highest quality holographic images. We supply the best holographic recording emulsions in the world from 5x5 cm up to 60x80 cm. All wavelengths and specialized specs available. Polaris Research GroupHolographic materials in both plate and film include high sensitivity for pulsed and continuous lasers (typical ~7000 lines/mm for Ultimate Standard 15nm thickness) to very high resolution holographic reflection applications (~10,000 lines/mm for Ultimate Ultrafine 8 nm thickness).
Sensitivity for our most popular product, Ultimate Standard is 75 µJ/cm2, about the same sensitivity as the former 8E75HD Agfa material for continuous lasers, but with much better resolution and contrast. For our Ultimate Ultrafine, the sensitivity is a remarkable 100-200 µJ/cm2
This means only a 2 second exposure is required on 4 X 5 (10,2 X 12,7cm) Denisyuk hologram using a 10mW HeNe laser.
For reflection red holography, factory pre-swelled plates can be purchased, to obtain instant color control or non-pre-swelled for mastering applications. Color pre-shifts and spectral sensitivities can be specified. In all cases, washing, sensitizing, latensification, hardening or other laborious pre-treatments often necessary for other manufacturers materials are not requiredat all. Alternatively, conventional color control techniques may be used as well.
We also have a material for high resolution Lippmann photography (Ultimate Lippmann) |
