PFG-03C, panchromatic holography films

RotGruenBlau

The Material PFG-03C has smaller grain (8-12nm) than PFG-01 material (40nm), a high resolution of >5000 lines/mm and allows realization of full colour holograms. One can see better luminance due to small scattered light, but need high exposure power. The fine grain emulsion are suitable in particular for reflection holograms.

  • Description
Tab 1

This material is designed for the production of full-colour reflection holograms using CW laser radiation in the blue (457nm - Argon laser), green (514nm - Argon laser) and red (633nm -HeNe laser). This is an ultra fine grain emulsion (see grain distribution curve on Fig.1). Due to the very small grain size emulsion is also less sensitive than fine grain emulsions, has shorte life time and the emulsion processing is more difficult.

A spectral sensitivity curve of the PFG-03C material is shown in Fig.2. Diffraction efficiency versus exposure is shown in Fig.3. The maximum diffraction efficiency in the blue region is >25% and in the green and red regions >45%.

Typical sensitivity values for PFG-03C are 2mJ/cm2 and 3mJ/cm2 for the blue and red/green regions respectively. Recommended processing is given in table1, recommended chemistry - in table2.
