SMA Medium Power Laser Delivery Cable Assembly

Lightel supplies cable assemblies equipped with SMA connectors for medium power laser delivery in medical and industrial applications. These connectors are terminated with a free-standing, epoxyless fiber tip which prevents the ferrule from melting or the possible burning of epoxy. Also, the copper ferrule provides better heat dissipation than those found in traditional multimode connectors. In addition, the connector incorporates sapphire protection whereby a sapphire disc is inserted between the copper ferrule and the fiber tip to protect the ferrule from energy accumulation and return. Wavelengths from 400nm-2200nm and fiber sizes from 100µm-1000µm are supported.

Steel-armored protection tubing is used to ensure laser safety and all assemblies are offered in standard or customer specified lengths and colors. Angle polish, AR coatings, integral cladding mode strippers, water or air cooling, and other custom options are also available by request.
