Can I make Denisyuk type holograms on the VRP-M material with an Argon laser?
The quality will be poor as VRP-M requires high carrier modulation to achieve good diffraction efficiency. Since the Denisyuk technique is typical of small carrier modulation the brightness of the final reflection hologram will be disappointing. For Denisyuk type holograms with green laser radiation you should use PFG-03C or PFG-04. • Can I make Denisyuk type holograms on the PFG-01 material with a Krypton or HeNe laser? Yes. • If I use PFG-04 plates to contact copy a VRP-M glass reflection master with an Argon laser, will the brightness/depth of image and quality of the final copied hologram be superior or inferior to the master? Pretty much all the qualities will be better as the PFG-04 emulsion is grainless and over twice as thick as VRP-M. Hence the image will be brighter, clearer and you ll be able to see into the hologram to a larger distance. • Is there any difference between the visual quality of reflection holograms made on PFG-03M and PFG-01/VRP-M? Not particularly. • Can I u
