We have simplified processing to two optimized, low toxicity baths: A developer and a bleach.
This chemistry is available in pre-packaged form. All our materials have been optimized for this safe and easy processing. Other conventional formulations may also work well with some experimentation.
As these emulsions have been specially developed for Denisyuk Holography, this means that even low contrast fringes during your recording will result in a very high efficiency hologram.
Important to note when making reflection holograms: Due to the great dynamic range of the material, a low beam ratio, often needed in some other manufacturer’s low contrast materials, say 2:1, will produce very bright but over- modulated images. We recommend a beam ratio of 10:1 for reflection holography and as high as 30:1 for transmission holography for the best brightness and image contrast.
