In some optical application, lens, reflector and other micro-optics components are normally needed to be assembled on optical fibers' end face.
High temperature fiber with high temperature survivable coating and special epoxy, which makes it resistant for 260°C and reflowable as well.
High power fiber collimator & Focuser normally consists of a HT fiber such as gold-coated fiber, HT epoxy and optical lens.
MEISU's high power optical fiber is driven by a relay to control the prism to turn, thus switch the path.
