Visualizes UV light amount distribution by color density
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.
The color forming material in the microcapsules reacts to the UV light and changes color.
In order to cover a range of accumulated light amount, we offer the product in three types.
[High pressure mercury lamp]
The following are color characteristics generated by a high-pressure mercury lamp. However, please note that these color characteristics are values generated by using FUJIFILM light source and devices, so there may be differences in color density for a given amount of light due to difference and variations in individual lamps or environment.
|Type||Product size||Light amount|
|Roll type||Sheet type|
|UVSCALE L||4 - 60||0.1mm||Mono sheet type|
|UVSCALE M||270mm x 5mm||270mm x 200m (5 sheets)||60 - 700||0.1mm x 2||Two sheet type|
|UVSCALE H||700 - 6,000||0.1mm x 2||Two sheet type|
* Please note that these light amount measurement ranges are estimates using our own high pressure mercury lamps, and that these ranges will vary depending on the type of lamp used as a light source and on the ambient environment.
Light amount measurement range: For color density 0.30-0.75 in the standard color sample
** Applies to wavelengths in the 200 to 420 nm range
