Snap-On Collimators

Stainless Steel Snap-On Collimators are designed to "snap" onto a 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 perfomance. Both surfaces are multilayer anti-reflection coated, with ¡Ã 98% transmission at the peak wavelength. Divergence of the collimated output beam is dependent upon laser wavelength
Snap-On Collimators can be used ¡°as is¡±or mounted in the optiona HCF-N COLLIMA-TOR HOLDER, which secures the Snap-On Collimator for post mounting
All optics in all OFR Fiber-Optic Collimators and accessories are AR coated according to wavelength. Therefore, when ordering, specify wavelength as follows.

Snap-On Collimators with VariFocus

An OFR LLO-Series ASPHERIC Coupling Lens is mounted in the fine-threaded, spring-loaded adjust ment barrel, which is rotated to achieve optimum collimation.

OFR VariFocus "focusability¡± feature allows simple recollimation of the beam when using different wavelengths. Turning the knurled ring a mere fraction of a turn will recollimate the beam over the full transmission range of the Lens.

 

 

 

All Snap-On Collimators have
VariFocus features

 

NOTE : Output beam diameter and divergence may vary.


 

 

 

 

Divergence of the Collimated Output

from multimode fiber varies with the core diameter of the fiber. The following table lists the expected divergence of the out-put beam from the Snap-On Collimator according to the core diameter of the multimode fiber.

Optical Power Delivery Cable

 

 

 

Stability, high efficiency and ease of attachment and alignment describe OFR's Fiber Delivery Systems. A Delivery System consists of three component sections :

Input Couplers,
To provide stable and efficient coupling of collimated free beam laser energy of any wavelength, into the...

Delivery Cables,
Single-mode, polarization-maintaining or multimode, 3mm kevlar reinforced or optionally protected by armored shielding, of  any length, to deliver optical power to the...

Output Collimators,
To produce a collimated output beam in a wide choice of diameters.

OFR Optical Delivery Systems
are assembled from FiberBench components, such as:

FiberPorts for input, FiberCalbes for delivery, and Snap-On Collimators for collimated output; focus option is also available

Flexibility in design of the Delivery System is possible by combining the many options available using existing components.

Custom 3-output assembly.

Pigtailed Collimators

 

 

 

Pigtailed Collimators

CFS-T Pigtailed Collimators are designed for OEM applications. These are supplied with a 1-meter fiber pigtail. The input end of the fiber is normally cleaved.
The fiber and an AR-coated, aspheric microlens are rigidly potted inside the stainless steel Collimator body. In order to ensure optimum collimation, it is essential that the wavelength be specified whenordering.

 


 

Custom modifications for non-collimated applications or larger-than-standard beam diameters are possible. Pleaseinquire.
Insertion loss is £¼0.2dB. Back reflection(return loss) is £¾-55 dB on all SM models.
Pigtailed Collimators have a 1-meter fiber pigtail. For other lengths, order as dash-number. For example, for a 3-meter pigtail, order as CFS-T-E1550-3

Focusers

 

 

 

Pigtailed Focusers

Pigtailed Focusers terminate a 1-meter single-mode or multimode fiber pigtail. Like Snap-On Focusers, pigtailed Focusers focus at a fixed distance.

Two OFR LLO-Series Aspheric Coupling Lenses (one collimator, the other focuser) focus the output to a predictable Airy's Disc. Each micro double-aspheric lens is multilayer anti-reflection coated, with £¾98% transmission at the peak wavelength.
