Fiber-optic collimator lenses are made from high index glass to ensure low aberration. A solid spacer is used between the fiber and the lens to ensure a compact and robust collimator package.
Standard collimators are optimized for telecom applications, but can be adjusted to other wavelengths/applications. Optical Fiber These collimators are plano-convex spherical lenses to collimate light from singlemode fibers. The angled flat side of these lenses assures low back reflection when put in contact with an optical fiber. The curved side, due to high refractive index material, provides remarkable imaging capabilities. Those can be used for fiber-optic switches, DWDMs, fiber-optic attenuators, optical isolators and other applications. Optical Fiber Aspheric These aspheric collimators are similar to the spherical version to collimate light from optical fibers, except than the curved side is an aspheric surface optimized to improve collimation.

Used in X-ray diffraction, in order to obtain a low divergence and polychromatic beam
An associated filter (depending on wavelength) could limit the energy band of the spectrum of emission; then Kbeta radiation could be largely decreased. Up to now, different types of collimation are available.
If the collimator is directly linked to the source, the primary beam is poly chromatic. Associated with a graphite monochromator first or a parabolic mirror (without filters), the band width in energy becomes much more defined.
The mechanical holder allows to change collimator size without any beam adjustment.
Inner diameters vary from 0,3mm to 3,2mm.
Usually, point source is required for the used of collimators optics. They are mainly used for texture or stress measurements.

CLA, CLB, and CLD series collimators are high-performance fiber optic devices employing high quality aspheric lenses to achieve low wave-front distortion, low divergence, and diffraction limited beam quality. These collimators are not only ideal for targeting at long distances but also good for pair coupling at long working distances. CLC series collimators are spherical lens-based low-cost devices suitable for multimode applications. Beam size can be as large as 12 mm.

Fiber collimator arrays consist of lens arrays and fiber arrays, resulting in polished optical fibers inserted and glued together into an angled silicon V-groove.
Collimators come assembled for a specific wavelength range, number of fibers and fiber type. A new optical design and assembly technique provide perfect collimation of optical fibers while an angled ferrule/lens interface reduces back-reflection.
Exceptional beam quality, high transmission, low insertion loss
Pointing accuracy ¡Ü 0.05 degrees
Back reflection from collimator alone ¡Ü -55 dB
Package dimensions
Fiber collimator arrays may be used in collimation of light in DWDMs, fiberoptic switches, attenuators, optical isolators etc.

Collimating Optics: Plano-convex lenses; copper total reflectorReflective and transmissive collimating optics are used in beam delivery systems to maintain beam collimation between the laser resonator and the focusing optics. Reflective collimators typically use Cu total reflectors, while transmissive collimators typically use ZnSe lenses.
