Nanlite Adjustable Iris for Forza 60 & 60B Projection Attachment

Overview

The Nanlite Adjustable Iris (PJ-FMM-AI) is a precision beam-control accessory designed for use with the Nanlite Forza 60 and 60B projection attachment (FM-mount system).

This insert features an 18-blade iris diaphragm, allowing users to precisely control the size of the projected light beam—from a tight spotlight to a wider circular output—without changing lenses or repositioning the fixture.

Installed directly into the projector’s internal slot, the iris enables smooth and continuous adjustment of beam diameter via an external lever, giving lighting designers full control over light shaping, focus, and intensity falloff.

Unlike gobos (which create patterns), the iris is used to produce a clean, variable circular beam, making it ideal for theatrical lighting, spotlight effects, product highlights, and controlled accent lighting.

The precision blade design allows for:
• Crisp, well-defined beam edges for sharp projection
• Smooth transitions when softening the beam using projector focus
• Rapid on-set adjustments without swapping accessories

Built for professional environments, the iris is constructed from heat-resistant materials to ensure durability when used with high-output LED fixtures.

This accessory is a core component of the Nanlite projection ecosystem, providing essential beam shaping control for cinematographers, photographers, and lighting technicians.
