Thickness of BW Film and Paper Emulsions

I want to learn the thickness of BW Photographic Film and Paper emulsions.





PS: One of my dearest friend sent me an pm. I think he does want to be anonym. THANK YOU.

Here is his reply :

Here is part of a 1963 paper on film emulsions in which the stated emulsion thickness is approximately 10μm - micrometers (10E-6m = 10,000E-9m = 10,000 nanometers or about 0.0004 inch).

Here’s an article on X-ray film indicating the emulsion thickness is 5 to 10 micrometers (μm) per side (X-ray films usually have emulsion on both sides). This is 5000 to 10,000 nanometers.

In the following article the emulsion of modern camera film is stated to be about 0.0006 inches in thickness (0.0006” = 0.00001524m = 15240E-9 m = 15240 nm). See “Coating Process”.

In this article film emulsion thickness range from 0.30 to 0.70 mils (1 mil = 0.001” = 2.54E-6m) or 7620 nm to 17780 nm.

Further down into the article, there is a table showing Kodalith Ortho PB Film, Type 3 (5 mil base) as having an exposed [to generate silver density] and processed emulsion of thickness 0.23 mil (5842 nm).
