Uvscale Photosensitive Film for Measuring UV Light Irradiation Distribution
Fuji Uvscale Film L: Overview
The Uvscale film was recently introduced by Fuji Film to enable the verification and study of light distribution determined by an UV source.
To better address the variety of potential uses for Uvscale, Fuji Film has developed this product line across different measurement ranges to
cover most applications. Specifically, the Uvscale L film represents the lowest grade available in the Uvscale product range. In manufacturing
and production contexts, verifying the correct intensity of UV light applied, as well as its actual coverage of the treated area, is essential.
The ability to monitor this important parameter allows for timely replacement of UV lamps when their light output decreases, improving production
quality and enhancing process repeatability. The Uvscale product range provides a useful methodology for studying, analyzing, and verifying surface
UV irradiation phenomena. It does not require specific skills or technical knowledge for use. The Uvscale photosensitive film is straightforward,
quick, and intuitive to use, and does not need special preparation. From the very first use, the image impressed with various shades of blue will
clearly visualize UV irradiation distribution, which can be interpreted by direct comparison with the provided colorimetric reference chart or
through more accurate and repeatable electronic measurement methods.
Fuji Uvscale Film L: Key Features

good repeatability of results obtained in measurement campaigns;
availability of optional electronic analysis systems;
simple and intuitive use.
Fuji Uvscale Film L: Technology Overview
Depending on their measurement range, Uvscale films are available in two different formats: single and double sheet.
The most sensitive sheet (L) is a single sheet type, used directly with the UV light source, while the other gradations (M and H)
involve a second sheet with photo-reducing characteristics, which alters the operational range of the sensitive Uvscale film.
The Uvscale film with the L range is available only in a single sheet version (mono sheet type). This single sheet type consists of a
sensitive sheet coated with a highly uniform layer of microcapsules (using proprietary PSC - Particle Size Control technology), which contains
a substance that changes color in response to absorbed UV radiation.
When the Uvscale film is exposed to UV light, the dye contained in the microcapsules changes color, and the new color density can be visually assessed
against the film's white background. This allows for comparison using the color scale provided with the product.
If you have any doubts, further useful information can be obtained by consulting the FAQ Uvscale

Fuji Uvscale Film L: Usage Instructions
It is advisable to prepare the Uvscale L film well in advance of the test, allowing the films to acclimate to the environmental conditions in which
they will be used. Unroll a sufficient amount of film for the test, ensuring that it rests on a clean, dry surface, preferably in dim lighting.
These preparatory actions will help the films settle, making the subsequent cutting and positioning operations easier, as described in the sequence
below. During these operations (and those that follow), place only the glossy sides of the films on the work surfaces, as the matte sides are the
ones that, when combined, determine the density and distribution of the recorded coloration. This will help prevent any accidental contact that
could affect the films before the tests.
Cut the Uvscale L film sheet to the desired dimensions using a simple pair of scissors. Since this grade of Uvscale (L) consists of a single film,
ensure that the cut sheet is appropriately sized for the area to be tested.
Handle the Uvscale L film with care, avoiding any dirt or creases on the sheets to be tested. The single sensitive film should be placed with
the glossy side facing down on the surface, while the matte side should be exposed to the UV light source being tested.
Ensure that the work area to be tested is adequately prepared and cleaned, and verify the correct positioning of the ultraviolet light source in
advance. Once the Uvscale film is properly oriented, position it in the area to be tested.
Activate the UV light source to begin the emission of ultraviolet light for analysis. For details on how to conduct the test, such as light
intensity and type of UV source, refer to the instruction manual provided with the Uvscale film.
Deactivate the UV light source to conclude the test. Remove the exposed Uvscale film from the work area.
The Uvscale film will now display the mapping of the UV light exposure zones detected.
Evaluate the results of the test using the instruction manual provided, which includes the colorimetric scale and reference charts.
The film will show the mapping of the UV exposure applied, recording the intensity of the detected UV light based on the developed color density.
This can be visually compared with the colorimetric chart to assess the UV irradiation levels.
THE NEXT STEPS ARE OPTIONAL AS THEY REQUIRE ADDITIONAL ANALYSIS TOOLS, WHICH ARE AVAILABLE FOR SEPARATE PURCHASE.
Where more accurate and repeatable evaluations of the results obtained are necessary, it is possible to scan the impressed films (for example,
using an Epson™ Perfection scanner) to obtain electronic images. These images can be saved, stored, and archived for future comparisons, and can
also be analyzed using optional support software.
Once digital scans of the Uvscale films impressed by the analyzed event have been prepared, you can use the optional FUD-7010E support software to
perform additional analyses. This includes tasks such as evaluating colorimetric results using false colors, rendering three-dimensional profiles,
and measuring the amount of light exposure, among other functions.
See package FUD-7010E for more details.
