OPTI-SCULPT
Rosco OPTI-SCULPT
Precision optical lenses that reshape a beam — stretch it into an oval or line, spread it evenly, or smooth a hotspot — without changing the fixture. 11 engineered patterns, symmetric and asymmetric. Here is the full angle chart.
Engineered optics that reshape a beam
OPTI-SCULPT is a precision-engineered optical lens that changes the shape and spread of a beam. Where a generic frost simply scatters and dims light, OPTI-SCULPT is designed to redirect it — elongating a round beam into an oval or a line along a chosen axis, or spreading it evenly to smooth out hotspots and scallops.
Because it works with the beam a fixture already produces, it solves a common problem cheaply: a luminaire that's right in every way except its beam shape. Rather than re-specifying hardware, you reshape the light at the front of the fixture.
11 spreads, symmetric & asymmetric
Symmetric patterns widen a round beam evenly; asymmetric patterns stretch it along one axis into an oval or line — rotate the lens to set the direction.
| Pattern | Type | Effect | Use |
|---|---|---|---|
| 10° / 20° / 30° | Symmetric | Even round spread, narrow → wide | Flood or soften a beam |
| 40° / 60° reversible | Symmetric | One lens, two spreads by face | Wide PAR-like wash |
| 10°×20° / 10°×30° / 10°×40° | Asymmetric | Gentle to strong oval stretch | Ovalise a beam |
| 10°×60° | Asymmetric | Strong linear streak | Wall-wash & uplight columns |
| 15°×35° / 15°×45° | Asymmetric | Medium oval | Match tall, narrow elements |
| 20°×40° | Asymmetric | Medium PAR-like oval | General shaped wash |
Rotating an asymmetric lens 90° swaps a horizontal stretch for a vertical one. Films are clear polycarbonate, cut to fit any gel frame or fixture. Not for use with UV / blacklight sources.
Redirect, don't just diffuse
Directional stretch
Elongate a beam along one axis — round into oval or linear — to match columns, corridors, artwork and reveals.
Smooth & even
Engineered spread evens out hotspots and scallops for clean grazing and wash, with less light loss than generic frost.
Keep your fixture
Reshape the distribution of a luminaire you've already chosen — no hardware re-specification needed.

Tall columns, controlled beams
For the Hamburg staging of MJ — The Michael Jackson Musical, Rosco Miro Cubes with OPTI-SCULPT lenses light full column heights with clean, contained beams rather than spilling across the surrounding surfaces.
It is the same principle used to graze a pier or wash a fin: shape the beam to the element, and the light reads as detailing, not general brightness.
Shape a beam before you specify
Beam shaping is easy to see and hard to describe. We can supply an OPTI-SCULPT sample kit so you can hold each pattern in front of your own fixture and watch the beam stretch, spread or smooth on your surface.
We put the lenses in your hands to trial; we don't run the tests on your fixtures for you. Once the shape is right, we confirm the pattern and cut and supply it in Australia.
Fighting a beam that won't fit?
You have the 11 patterns and the numbers. Tell us the fixture and the surface, and we'll help trial the right OPTI-SCULPT lens and supply it in Australia.
