Snap-On Collimators

Stainless Steel Snap-On Collimators are designed to "snap" onto an FC or SMA connectorized fiber to produce a collimated beam. Snap-On Collimators contain a micro, double-aspheric lens, which is designed for diffraction-limited performance. Both surfaces are multilayer anti-reflection coated, with > 98% transmission at the peak wavelength.

Divergence of the collimated output beam is dependent upon laser wavelength and fiber core diameter.  Snap-On Collimators can be used "as is", or mounted in the optional HCF-N COLLIMATOR HOLDER, which secures the Snap-On Collimator for post mounting (8-32 and M4), or in 1-inch mount. The collimators have ~ 1.5mm of adjustment for Z translation.

All optics in all OFR Fiber-Optic Collimators and accessories are AR coated according to wavelength. Therefore, when ordering, specify wavelength as follows.

Wavelength Range (-5, -8, -11)	Order as
450 - 600 nm	VIS
550 - 750 nm	VIR
750 - 960 nm	NIR
960 - 1100 nm	YAG
1275 - 1600 nm	IR
Ex. CFC-5-NIR, CFC-2-YAG etc. We often have coatings that overlap. When ordering please indicate the operating wavelength. This will let us pick the best coating avalable for your application.

For fiber coupling applications we recommend using our PAF series FiberPorts and for fiber-fiber coupling see our FiberBench systems.
