The invention relates to an apparatus for light fastness testing. The apparatus for holding samples for testing comprising a planar member and vacuum to hold a sample against the test area of the planar member. A heating and cooling device in contact with said planar member, a heat sink, in contact with the heating and cooling device and a fan to direct air over the heat sink.

Sample holder for accelerated fade apparatus and method of its use

The invention relates to an apparatus for light fastness testing comprising a light source, means for dividing ultraviolet and visible light from infrared rays, means to direct the visible component of light into spherical cavity, and means to mount test samples in apertures in said cavity.

Accelerated fade apparatus and method of its use

A method and apparatus (10) referred to as a step and repeat sensitometer directs radiant energy (18) from a radiant energy source (16) into a diffuse integrating chamber (2) which uniformly mixes and directs the radiant energy (18) onto an exposure plane (14) where a radiation sensitive sample (1) is positioned so that individual areas of the sample (1) are exposed to readily adjustable levels of illuminance producing gradated exposures.
