  • UV Light Distribution Mapping System

FujiFilm Corp., Industrial Products Div.Request Info
Visualizes UV light amount distribution by color density

FujiFIlm UVScaleStructure

One side of the base film has a UV light sensitive layer, with the opposite side having a white-colored layer. The light sensitive layer changes color according to the amount of UV light it receives, so the amount of light distributed on the exposed surface is easily seen by observing a light sensitive layer and white-colored layer are attached to the base. Since the color density of the white-colored layer corresponds to the amount of UV light received, the light amount distribution on the light receiving surface can easily be investigated.

FujiFilm Example Applications


The color forming material in the microcapsules reacts to the UV light and changes color. 

How To Use

After cutting UVSCALE to the required shape (length), place it on the location that you want to measure.
Operate the equipment or device, and expose UVSCALE to UV light. * The side of UVSCALE with matt surface should be exposed.

The UVSCALE changes color in accordance with the amount of light.

Remove UVSCALE, and determine the distribution of light by observing the color distribution. * Use the matte side for observing.

Electromagnetic radiation detectable by the eye, ranging in wavelength from about 400 to 750 nm. In photonic applications light can be considered to cover the nonvisible portion of the spectrum which includes the ultraviolet and the infrared.
