Refocusing and Collimator Assemblies- LC-4, LC-10, and LC-22 Series Assemblies

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 fixed 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).
