In this paper, we report the reliability test results of transmission-type holographic optical elements made with DuPont photopolymer HRF-600. The reliability tests performed in this study include 6000 cycles of liquid-to-liquid thermal shock cycling, 2200 cycles of air-to-air thermal cycling, 1500 hours of humidity test, and 675 hours of burn- in test at 125 degrees C. A total of 210 holograms was tested, with 532 data points collected for efficiency measurements. The results show that the average efficiency change after these tests is negligible and that the standard deviation is only approximately 10 percent.
