About Adox CMS 20 II

The spectral sensitivity of ADOX CMS 20 differs only slightly from that of other slow speed films. When designing the emulsion special care was taken to achieve a superior tonal differentiation. CMS differs very good between red and blue. His sensitivity ranges from 400nm just until 650 nm. He is thus an orthopanchromatically sensitized film. ADOX CMS 20 is a monodisperse, ultrahigh resolving document-film. In order to make this material usable for pictorial photography ADOX developed the ADOTECH (Not Included) chemistry system which leads to superior results.

Film Type
Silver halide recording material with an anti-halation layer in between emulsion and film base yielding highest sharpness and resolving power. Light cannot diffuse within the base layer.
