Colour Ultra-fine grain photomaterials for holography

Guaranteed material lifetime - 6 months

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).

A spectral sensitivity curve of the PFG-03C material is shown in Fig.1. 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. The grain size distribution curve for both PFG-03C is shown on Fig.2. Difraction efficiency - on Fig. 3.

Recommended processing is given in table below.

This material is designed for reflection hologram recording using CW radiation in the red spectral range (633nm - HeNe laser and 647nm - Krypton laser). The spectral sensitivity curve of the material is shown in Fig.1, diffraction efficiency - on Fig. 3. Grain size of this material is 20-30nm.

Peak emulsion sensitivity is around 1.5-2mJ/cm2. Recommended processing is given in table below.
