This Silver Halide photomaterial is used in art holography (one or two steps holograms recording). Resolution: more than 3000 lines/millimeter.
The largest standard film width is 35 centimeters. Custom film substrates sizes are available for the coating on request. Guaranteed material lifetime – 10-18 months.
Characteristic curve of red sensitive PFG-01 emulsion, showing spectral sensitivity versus wavelength, is shown in Fig.1. As it is seen from the curve – PFG-01 works well in red regions of spectrum, showing the peak at approximately 100 microJoule/cm2 (~640 nm).
Fig.2 shows the optical density after PFG-01 exposure by CW radiation and after development versus energy. Grain size is shown in Fig.3. The diffraction efficiency versus exposure for reflection holograms recorded on PFG-01 (using a CW laser) is presented in Fig.4. The maximum observed diffraction efficiency >45%.
Processing and Handling Recommendations
- Unseal and process in indirect non-actinic light with use of a dark-green light filter (transmission zone 470-550 nm.
- Temperature of processing solutions – 20°C.
- Storage condition: Humidity 65% and 12-15deg. Celsius.
Recommended Chemical set of SM-6 developer and PBU-Amidol bleach can be obtained from our web shop.
|Recommended PFG-01 processing|
|Development||SM-6 , 2min (or until density 1.5)|
|Bleach||PBU-Amidol until clear (~2-3 min) plus 2 min|
|Wash||Water 5 min.|
|Final Wash||Water with wetting agent (Agepon) 1min|
All material performances given herein are guaranteed only for the use with the recommended chemistry. However, for CW works in conventional holography one, on own risk, may also use the standard Kodak D-19 developer (3 min.) and Sulfuric- Potassium dichromate bleach (2-3min. : 30ml sulfuric acid + 5gm potassium dichromate + 1 liter of water).
