1. Number of Films: 

• Specifically designed to hold two X-ray films simultaneously.

2. Illumination:

LED Lighting:

High-quality LED bulbs are commonly used for their energy efficiency, brightness, and long lifespan. 

Brightness:

Features a dimmer to adjust the brightness level for optimal viewing of different film densities. 

Uniformity:

The light should be distributed evenly across the viewing area to prevent shadows and ensure consistent visibility. 

3. Construction and Materials:

• Cabinet: Typically made of a sturdy material like powder-coated MS (mild steel) or aluminum.
• Viewing Surface: A durable acrylic sheet or plexiglass is used as the viewing surface to allow light to pass through and hold the films securely.
• Frame: A metal frame provides structural support and stability.

4. Dimensions: 

Viewing Area:

Dimensions vary, but generally, the viewing area is designed to accommodate standard X-ray film sizes (e.g., 14" x 17").

Overall Size:

The external dimensions of the view box will be larger to accommodate the frame and other components.
