Collimator
These collimators are designed to connect onto the end of an FC/PC, FC/APC or SMA905 connector and contain an AR-coated aspheric lens. The laser with fiber coupled to a MM4 fiber (200µm core diamter) has a beam diameter of 200μm and a beam divergence of 25° (without collimator). SLOC can provide one collimator. It can collimate the beam after MM4 fiber to 20mrad. The collimator also can protect the fiber end from dust.
	Focus	Beam Diameter	Beam Divergence
Collimator 1	10mm	4.0~6.0mm	10~30mrad
