These are light transmitting single core optical fibers. They offer an economical and convenient method of transporting energy from light sources to samples, or from samples to spectrometers or detection systems. They are particularly useful for long distance applications. We offer 1 and 2 m length SMA terminated fibers. Contact us for other lengths and/or terminations - we welcome custom inquiries.
We offer two families, differing in transmittance ranges. See Fig. 1 for the typical transmittance of both fiber materials.

Two Types of Fibers Available
UV-VIS Fibers
These fibers have a high purity UV grade silica core and silica glass cladding. Their usable range is 250 to 2000 nm and they have a high damage threshold; for a clean input surface the damage threshold is 100 kW cm-2 in the NIR or 10 J cm-2 for ≥1 ns pulses, for wavelengths above 360 nm.
VIS-NIR Fibers
These fibers have a water free silica core to reduce absorption in the NIR. We also offer Infrared Fibers which transmit to 18 Μm.
