The KUPO ETI-F24 is a 24-leaf manual iris for S4 / Shakespeare / S3 / Marumo Rayer. Compared with an 18-leaf iris, the 24-leaf construction gives the beam a finer circular edge when the aperture is reduced.
Why It Matters
Some specials need the beam to close down smoothly without the edge feeling too segmented. ETI-F24 gives designers and technicians the finer leaf count, heat-resistant construction, and familiar accessory-slot handling needed for more controlled profile work.
Key Features
24-leaf construction creates a smoother circular aperture than lower-leaf-count iris designs
Adjustable 4.5 mm to 75 mm aperture range supports tight specials and open beam looks
Stainless steel leaves with formulated gray paint resist heat up to 450 °C
Three fixed focusing holes make insertion and positioning more repeatable
Tailor-made backing plate option supports special fixture adaptations when requested
Applications
A practical accessory for stage, studio, and venue profile fixtures where smooth aperture control is needed for specials, isolation, spill reduction, or cue refinement.
Compatibility
Compatible with S4 / Shakespeare / S3 / Marumo Rayer, with listed dimensions A 120 mm, B 137 mm, C 13 mm, and D 102 mm.
Frequently Asked Questions

Can this be used with Marumo Rayer fixtures?

Does it include motorized control?
