Uvscale photosensitive film for measuring the distribution of UV light irradiation.
Fuji Uvscale Film M: Overview
The Uvscale film has been recently introduced by Fuji Film to allow for the verification and study of light distribution from a UV source.
To better meet the diverse range of possible applications for Uvscale, Fuji Film has developed this product family, offering different measurement
ranges to cover most applications. Specifically, the Uvscale M film is an intermediate-grade film available in the Uvscale product range.
In manufacturing and production environments, there are numerous situations that require verification of the correct UV light intensity applied
and its effective coverage over the treated area. The ability to monitor this crucial parameter allows for timely replacement of UV lamps when
their light output decreases, improving production quality levels and ultimately increasing process repeatability.
The Uvscale product range is an effective methodology for studying, analyzing, and verifying UV light irradiation phenomena. Its use does not
require specialized skills or technical knowledge. The Uvscale photosensitive film is very simple, quick, and intuitive to use, and does not
require specific preparation. From the first use, the film will display varying levels of blue, providing a clear visualization of UV irradiation
distribution, which can be interpreted by direct comparison with the provided colorimetric reference chart or through more accurate and repeatable
electronic measurement tools.

colorimetric table included (for visual assessment);
availability of optional electronic analysis systems;
simple and intuitive use.
Fuji Uvscale Film M: Technology Overview
Based on their measurement range, Uvscale films are available in two formats: single-sheet and double-sheet.
The more sensitive sheet (L) is a single-sheet type used directly with the UV light source, while other grades (M and H) are obtained using a
second sheet with photosensitive properties, which modifies the operating range of the sensitive Uvscale film. The Uvscale M film is available
only in a double-sheet version. This type consists of a sensitive sheet with an extremely homogeneous layer of microcapsules
(proprietary PSC - Particle Size Control technology) that change color based on the absorbed UV radiation, and of an additional photosensitive
sheet that acts as a filter between the light source and the Uvscale sensitive film.
This configuration allows for a more precise measurement and filtering of UV light, suitable for a range of applications.
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
(thanks to the white background of the film support), using the provided color scale. To prevent color saturation of the film, additional Uvscale
grades are achieved by using the second film provided (grades M and H), which features photosensitive properties. This second film acts as a filter,
moderating the amount of UV exposure impacting the Uvscale film.

Fuji Uvscale Film M: Usage Instructions
It is advisable to prepare the Uvscale M films well in advance of the test to allow the films to adjust to the environmental conditions in which
they will be used. Unroll an adequate amount of films for the test to be conducted, ensuring they rest on a clean, dry, preferably dimly lit
surface. These preparatory actions will allow the films to settle, simplifying the subsequent cutting and positioning operations described in the
sequence below. During these operations (and those that follow), place only the glossy sides of the films on the work surfaces (the matte sides
are the ones that, when combined, determine the density and distribution of the recorded color) to avoid any accidental contact that could affect
the films before testing.
Proceed to cut the Uvscale M films to the desired dimensions using a simple pair of scissors. Since it consists of two films (a photo-reducing film
and a sensitive film), ensure to cut both films that make up the Uvscale Film, making sure that the dimensions are appropriate for the area to be
tested.
Handle the Uvscale M with care, avoiding any contamination or bending of the sheets to be tested. Overlap the two films so that the cut shapes match
for both sheets. The sensitive film should be placed with the glossy side down on the surface, while the matte side should be covered by the
photo-reducing sheet. Be sure to account for this arrangement during the cutting process.
Ensure that the work area to be tested is properly prepared and cleaned, and check the correct positioning of the ultraviolet light source in advance.
After correctly aligning the two Uvscale films, proceed to place them in the area to be tested.
Activate the UV light source to start the emission of the ultraviolet light to be analyzed. For details on how to conduct the test (e.g.,
light intensity, type of UV source, etc.), further information can be obtained from the instruction manual provided with the Uvscale film.
Deactivate the UV light source to conclude the experiment. Remove the exposed Uvscale film from the work area.
The Uvscale films will now display the mapping of the UV light exposure areas.
Evaluate the results of the test using the instruction manual provided, which includes a colorimetric scale and reference charts.
The film will display the mapping of the applied UV exposure, recording (based on the developed color density) the intensity of the detected
light exposure. This can be visually assessed by comparing it with the colorimetric chart.
THE FOLLOWING STEPS ARE OPTIONAL AS THEY REQUIRE THE USE OF ADDITIONAL ANALYSIS TOOLS THAT MUST BE PURCHASED SEPARATELY.
Where more accurate and repeatable evaluations of the results are needed, it is possible to scan the impressed films (e.g., using an Epson™ Perfection
scanner) to obtain electronic images. These images can be saved, stored, and archived (for future comparisons) and, most importantly,
can 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 further analyses. These analyses may include evaluating colorimetric results using false colors, rendering three-dimensional profiles,
measuring light exposure, and more.
