In this research work, high diffraction efficiency and transmission phase holographic lens is recorded by using red sensitive commercially available fine grain PFG-01 silver halide holographic emulsion. In the preliminary stage, the exposure sensitivity is optimized and the plates were chemically developed in recommended developer of CWC2 by the supplier. In the next stage, we have modified the developer and the holographic lens was recorded for the same optimized energy level for comparison. The phase holographic lens was a result by using modified fixation-free rehalogenating bleach R10 for modified and unmodified CWC2 developer. The obtained diffraction efficiency for the holographic lens in usual processing technique is compared with our new modified CWC2 developer. As a result, the enhancement of diffraction efficiency of nearly 20% was achieved by using the new combination of modified developer and modified bleach as compare to the usual combination of developer – bleach processing technique. The experimentally obtained results are compared and explained in detail.
