11. Absorption of UV radiation causes CDOM to " bleach ", reducing its optical density and absorptive capacity. 12. Its optical density is lower than nylon, which makes the line less discernible to sharp fish eyes. 13. Generally, the optical density of the stain increases in the heavily exposed ( and heavily developed ) area. 14. Unless these cells happen to be directly in the light path, their growth will not affect optical density readings. 15. "' Tailing "'is a defect in printing consisting of a rapid change of optical density when printing solid graphics. 16. Alternatively a common method which is applied to remove broad-band structures from the optical density are binomial high-pass filters. 17. The old nomenclature for this value was optical density ( OD ), current nomenclature is absorbance units ( AU ). 18. The resulting effect is that less light will strike the photodetector and this will produce a higher optical density ( OD) 19. "' OD600 "'is an abbreviation indicating the absorbance, or optical density , of a sample measured at a wavelength of 600 nm. 20. Such a distribution increases the surface area of the material in the rings, leading to high optical density in back-scattered light.
