## Intended Use

The Diffuser Panel is designed to diffuse the light from the light source in Radiographic Film Illuminators.

## Device Story

Diffuser Panel functions as a component for radiographic film illuminators; consists of light diffusing layers, brightness enhancer films, and a scratch-resistant polycarbonate cover. Device installed in illuminator housing; operates by diffusing light from internal source to provide uniform illumination across x-ray film. Used in clinical settings by radiologists or clinicians to facilitate diagnostic review of radiographic images. Provides consistent light distribution to aid visual interpretation of films.

## Clinical Evidence

No clinical data; bench testing only. Equivalence based on functional comparison of light diffusion and distribution characteristics.

## Technological Characteristics

Components: light diffusing films, brightness enhancer films, scratch-resistant polycarbonate panel. Function: light diffusion and uniform distribution. Form factor: panel insert for radiographic film illuminators.

## Regulatory Identification

A radiographic film illuminator is a device containing a visible light source covered with a translucent front that is intended to be used to view medical radiographs.

## Predicate Devices

- Diversified Diagnostic Products Radiographic Film Illuminator panel ([K875233](/device/K875233.md))

# 510(k) SUMMARY CONTINUED

## 4. Description of the device

The Diffuser Panel consists of layers of light diffusing and brightness enhancer films, plus a clear polycarbonate panel that is coated with a scratch guard to protect the surface of the brightness enhancer from scratching.

## 5. Intended use of the device

The Diffuser Panel is designed to diffuse the light from the light source in Radiographic Film Illuminators.

## 6. Comparison of technological characteristics with predicate device

The function of glass or plastic translucent panels is to diffuse light, and distribute bright light evenly over the x-ray film. The Focused Viewer Diffuser Panel is composed of plastic and is designed to diffuse light and distribute light evenly over the x-ray film in a manner equivalent to marketed devices and to provide at least equivalent brightness.
