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.
Range (-5, -8, -11)
450 - 600 nm
550 - 750 nm
750 - 960 nm
960 - 1100 nm
1275 - 1600 nm
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.
