Spectra announces the introduction of three new series of fibre
optic collimator and refocusing assemblies. The LC-4 Series with a
4.0 mm aperture, the LC-10 Series with a 10.0 mm aperture and the
LC-22 Series with a 22.0 mm aperture.
Spectra's standard collimators employ plano-convex lenses positioned
at their focal length from the optical fibre tip, and are used to
expand the beam and decrease the divergence of light exiting from an
optical fibre; conversely, light entering a collimator will be
focused into the fibre. The LC-4 series are housed in stainless
steel, and the LC-10 and LC-22 are housed in anodized aluminium. SMA
terminations are standard, and all are available with several
options, including FC, ST and SC connectors, various Numerical
Apertures (N.A.), and AR coated optics. Refocusing assemblies are
available in several focal lengths for LC-10 and LC-22 collimators.
