High quality Mitsubishsi/Eska PMMA fiber for lighting supplied in bulk quantities.

Core material	Polymethyl Methacrylate
Cladding material	Fluorinated Polymer
Refractive index	1.49
Numerical aperture	0.5
Refractive index profile	Step index
Operation temperature range	-55°C to +70°C in low humidity; <60°C at 95% RH (attenuation change is within 10% after 1000 hours except for that due to absorbed water). Please note that fiber can become brittle at lower temperatures.
