0.75 mm PMMA End-Glow Bare Fiber, 2700 m Roll for Star Lighting
Bare 0.75mm PMMA end-glow POF, step-index, NA 0.5, 200 dB/km, -55 to +70 C, bend radius >=10x, on 2700m rolls for star ceilings.
The 0.75 mm PMMA end-glow fiber (family row L03) sits between the fine 0.5 mm SK20 and the brighter 1.0 mm L04 grades. It is a bare step-index fiber that glows at its cut end, supplied on 2700 m spools.
Product Overview
0.75 mm gives a brighter and more robust light point than 0.5 mm while remaining flexible enough for dense star ceilings and fiber curtains. Light is introduced at one end by an LED illuminator and exits only at the polished far end.
The supplier sheet also lists a cladding refractive index of 1.363 and a minimum bend radius of 10× the fiber diameter. Roll length is 2700 m per spool, matching the folder.
Key Features
- 0.75 mm OD / 0.735 mm PMMA core, step-index, NA 0.5.
- Bright pinpoint end output from a matched LED illuminator.
- Bend radius ≥10× diameter; -55 to +70 °C.
- 2700 m roll for medium-density lighting jobs.

FAQ
How does 0.75mm compare to 1.0mm end-glow fiber? 1.0mm collects more light and gives a brighter end point, but is stiffer and bulkier. 0.75mm is a good compromise for dense layouts where 1.0mm fibers would touch; both use the same PMMA material and illuminators.
