UVSCALE

Visualizes UV light amount distribution by color density

Features

Structure and how it works

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.

Reducing light film

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.

  • * 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.
  • *4 Standard Color Samples show the density range for visual evaluation.
