 Our standard Fiber
Optic Collimators employ plano-convex lenses positioned at their
focal length from the optical fiber tip. The standard collimators
use SMA female connectors for ease of coupling to standard 0.22 N.A.
fiber optic cables. For light exiting
from an optical fiber, collimators expand the beam and decrease the
divergence by the ratio of the fiber core diameter to the collimator
aperture. Ex. A 100 µm core
diameter fiber with an N.A. of 0.22 has an output divergence of
±12.7°. When coupled to an LC-4, its divergence is reduced to
0.100/4.00 x ±12.7°
±0.3° at its center wavelength. Conversely, light entering the
collimator will be focused into the fiber.
Our UV-Vis and Vis-NIR
Refocusing Assemblies are offered for the LC-4, LC-10, and LC-22
series collimators. These single-element cells thread into the
collimator, refocusing the beam at a given distance. Standard
refocusing assembles are listed above. Other focal lengths and AR
coated optics are available on a custom basis.
OTHER AVAILABLE OPTIONS: FC, ST and SC connectors, .25" ferrules;
Operation with other N.A.’s such as 0.12,
0.26, 0.37, and 0.40; AR coated optics for > 98% transmission
at peak wavelength. |

LC-4 SERIES COLLIMATOR ASSEMBLIES
These are
tunable assemblies with a 4.0 mm aperture within stainless steel
housings of 6.35 mm (.25") O.D. x 23.25 mm length. Identify the
actual operating wavelength when ordering and the assembly will
be factory aligned for that range. Collimator Assemblies
include female terminations which mate directly to fiber cables
(SMA standard .25", FC, ST, OQ, others available).
*
"-THD"
designates an internal thread, which is required to mount an
LF-4N refocusing assembly. Use these collimators, if you plan to
attach a refocusing assembly to the collimator. |

LF-4
SERIES REFOCUSING ASSEMBLIES
These are
tuned assemblies with a 4.0 mm aperture within stainless
steel-303 housings of .25" O.D. x .25" length (excluding
threaded section). Note: Refocusing Assemblies mate to
Collimator Assemblies; they do not mount directly onto fiber
optic cables.

LC-10
SERIES COLLIMATOR ASSEMBLIES
These
are tunable assemblies with a 10.0 mm aperture within black
anodized aluminum housings of 19.0 mm (.75") O.D. x 40 mm
length. The stainless steel SMA “plug” can be positioned and
set-screw locked for optimum collimation. Collimator
Assemblies include female terminations which mate directly to
fiber cables (SMA standard .25", FC, ST, OQ, others available).
