Silver Bromide Emulsion Types in X-Ray
1. Monochromatic Emulsion - No colour sensitizers added, so emulsion will be sensitive to the blue-violet spectrum of the light.
It usually requires prolonged exposure to red light to produce any Photographic Effect on the film. This is the reason why RED LIGHT is used in dark rooms.
2. Orthochromatic Emulsion - Spectral Resolution extended upto green(570nm), with colour sensitizers added.
3. Panchromatic Emulsion - extended upto Red light.(700nm).
