Shape & Control Light
Make the beam fit the building.
Turn a round beam into a linear or oval one, stretch it along a corridor or artwork, soften a hotspot, or hold a precise shape on a wall — without changing the fixture. Rosco OPTI-SCULPT and beam-shaping optics reshape the light an existing luminaire already makes.
When the fixture is right but the beam isn’t
Luminaires come with the beam the manufacturer gave them — usually round, often too wide, sometimes too even. Architecture rarely does. A column wants a tall, narrow wash. A long artwork wants a slot of light, not a circle. A grazing wall wants the hotspot smoothed out.
Rather than hunting for a different fixture — or accepting spill and scallops — you can reshape the beam the fixture already produces. Rosco’s OPTI-SCULPT is a precision optical lens that stretches, spreads or elongates a beam in a chosen axis, and other engineered diffusions smooth and control distribution.
It’s a small change at the fixture that solves a problem that would otherwise mean re-specifying the whole luminaire.
Engineered optics, not guesswork
Directional beam stretch
OPTI-SCULPT lenses elongate a beam along one axis — round becomes oval or linear — to match columns, corridors, artwork and reveals.
Smooth, controlled spread
Engineered diffusion evens out hotspots and scallops for clean grazing and wash, without the heavy light loss of generic frost.
Keep the fixture you chose
Reshape the distribution of a luminaire you’ve already selected or installed — no need to re-specify hardware to fix the beam.
Tall columns, tight beams
For the Hamburg staging of MJ — Das Michael Jackson Musical, Rosco Miro Cubes paired with OPTI-SCULPT lenses light full column heights with clean, controlled beams rather than spilling light across the surrounding surfaces.
It’s the same principle architects use to graze a pier or wash a fin: shape the beam to the element, and the light reads as intentional detailing rather than general brightness.
What to resolve early
Beam shaping is precise work. CFATS can trial lenses on your actual fixture and surface before specifying.
The element you’re lighting — its height, width and proportion — sets the beam shape you need. We work backwards from the surface.
OPTI-SCULPT works with the beam your luminaire produces; the starting beam angle affects the achievable result. We match lens to fixture.
Directional lenses have an axis — orientation at the fixture determines whether the stretch runs vertical, horizontal or diagonal.
Every optic costs some output; engineered lenses minimise it. We factor this into the brightness you’ll actually see.
