Structure
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.
Principle
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.
Reducing light film
In order to cover a range of accumulated light amount, we offer the product in three types.
Standard color chart
[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.
- *Each density is the value measured by FUJIFILM. It is not a warranty of density level.
- **The amounts of UV-light are values using a 365nm UV illuminometer.
- ***The solid lines on the graph show the recommended measurement range. The broken lines represent values that are not as precise as the solid lines and should be used as a reference only.
- *4Standard Color Samples show the density range for visual evaluation.
