Diffusion disc set EUROLITE 42109611 — 4 pieces, 9° beam angle each

Set of four EUROLITE diffusion discs, each producing a 9° light spread for precise beam shaping. These diffusion discs are designed to soften and slightly widen the output of compatible stage and studio fixtures, reducing hard edges and glare while preserving controlled projection. The set includes four identical discs that are easy to install and replace in fixtures that accept standard accessory discs, making them suitable for temporary setups and permanent installations where consistent beam quality is required.

Advantages

Each disc provides uniform diffusion with a fixed 9° spread, enabling consistent beam shaping across multiple fixtures. The discs reduce hotspot contrast and visible beam edges without significant loss of projection distance, allowing technicians to maintain focused lighting while achieving a softer appearance. Their compact design and standardized mounting make them quick to change during rigging or venue reconfiguration.

Key specifications

How to use

Install a diffusion disc into the accessory slot or holder of a compatible fixture according to the fixture manufacturer's instructions. Ensure the fixture is powered off and cooled before handling. Position the disc so it is centered in front of the light source to achieve an even 9° spread. For matching beam characteristics across multiple fixtures, install identical discs in each unit and verify alignment during focus. Replace or remove discs as required for different beam effects or maintenance.

Recommendations

Inspect discs for scratches or contaminants before installation; clean with a soft, lint-free cloth and appropriate optical cleaner if necessary. Avoid exposing the discs to high temperatures beyond the fixture's accessory specifications and store them flat in a protective case when not in use to preserve optical quality.
