Simmod Aria Gold Flare Filter (77mm)

Conventional flare filters typically rely on etched streak patterns or coated surfaces to generate flare artifacts.

The Aria Flare system introduces a physical light interaction layer positioned within the optical path.

The Simmod Aria Gold Flare Filter (77mm Circular) is a screw-in special effects filter designed to create controlled gold flare streaks, shafts, and light swirls when interacting with directional light sources.

Filter Format

• Rear thread size: 77mm
• Front thread size: 77mm
• Circular rotating filter design
• Available flare colors:
  • Gold
  • Blue
  • Red
  • Green

The front threading allows additional filters or accessories to be mounted if required.

Optical Function

The filter utilizes:

• Fine metallic thread embedded between two layers of optical glass

When exposed to directional or point-source lighting, the embedded metallic structure refracts and scatters light, producing:

• Linear flare streaks
• Light shafts
• Swirling flare artifacts
• Directional flare patterns

The resulting flare behavior varies depending on:

• Light source intensity
• Light source angle
• Aperture
• Lens focal length
• Rotation of the filter

The circular frame allows the flare orientation to be adjusted through 360 degrees by rotating the filter during operation.

Optical Construction

• HD Schott optical glass
• Laminated dual-glass structure
• Embedded metallic flare element
• Double-sided 14-layer nano coating

The coating structure is designed to reduce:

• Unwanted internal reflections
• Ghosting
• Surface contamination from oil, water, and dust

Mechanical Construction

• Precision-machined brass filter frame
• 360-degree rotating outer ring
• Matte black internal finish
• 6mm filter thickness

The brass frame is designed to maintain thread stability and reduce thread binding during repeated installation and removal.

Mechanical Performance

• Smooth rotational adjustment for flare orientation
• Fixed threaded mounting interface
• Compatible with matte box workflows using threaded adapters
• Designed for repeatable flare positioning

System Behavior

• Passive optical special effects filter
• No electronic components
• Does not modify internal lens mechanics
• Flare intensity and shape depend on scene lighting conditions and filter orientation

Compatibility

• Lenses with 77mm front filter threads
• Step rings may be used for alternate lens thread sizes
• Compatible with:
  • Spherical lenses
  • Anamorphic lenses

Notes

• Flare characteristics vary significantly depending on lighting direction and exposure
• Rotating the filter changes flare angle relative to the image frame
• Strong directional light sources produce the most visible effect
