Higher optical density

Web4 de mai. de 2012 · No, Optical Density is not related to mass density. Think of OD as a measure of a materials ability to pass light. The higher the OD the lower the amount of light which gets through. This will vary with wavelength for any given material. A pair of laser safety glasses I have is rated; O.D. 7 @ 190-400nm; 1.3+ @488nm ; 5 @10.4nm. WebA higher optical density indicates how much slower the wave travels through that material. The refractive index of the material is an indicator of its optical density. The dimensionless refractive index value indicates the number of times slower a light wave would travel in the medium compared to its speed in vacuum.
