These Green Sensitive Holographic Plates (2.5 x 2.5") from HARMAN technology can be used with a wide range of lasers including Solid State frequency-doubled Nd:YAG or Argon Ion gas lasers, both continuous and pulsed. The plates are coated with fine grain holographic emulsion. They are capable of more than 7000 cycles/mm and at 632 nm provide optical transmission better than 80%.
