Collimators
Collimators
Adjustable fiber collimators for 2 µm laser systems, with CF, SMA and QBH variants.
Overview
Collimation for fiber-delivered laser beams
The compact collimators support beam collimation in industrial equipment, optical experiments and laboratory systems. Infrared optical materials help limit losses.
Futonics also produces fiber connectors with anti-reflection coatings for laser powers up to 400 W. Connector type and supported laser power depend on the selected variant.
* Beam-diameter values are described by the source as theoretical beam properties before the collimator.
