How do extremes of humidity and temperatures affect Slavich Holography materials?
Very high humidity (>85%) should always be avoided as they will degrade the lifetime rapidly. Medium to low humidity are acceptable with low humidity being optimal. Temperatures above 80 Degrees C lead to the PFG-03 material becoming sensitive to the polarization of light. Also exposure to such high temperatures will produce a gradual decrease in sensitivity. Short exposures of all materials to temperatures up to 50 Degrees C will not affect performance or greatly reduce the lifetime. Transport of the materials through hot countries is generally not a problem. • Will the PFG-03M plates work with a HeCd laser of 40mW? The green (514nm) sensitivity is about 5x worse than the red (633nm) and 442nm is around 1.5 x better than the green. • What must my PFG03M plate look like after developing? This depends on the developer but usually this must be a light to deep brown. Initially the plates should be transparent/blue. Note that for VRP/M/PFG-01 the plates before development are transparent a
