Description
OZ Optics offers a complete line of high power fiber collimators and focusers with low backreflection, designed to collimate or focus light exiting a fiber to a desired beam diameter or spot size. These devices can be used with laser diodes, fiber lasers, acousto-optic modulators and other fiber optic devices. Collimators and focusers can be used as matched pairs to couple light in and out of optical devices. This makes them ideal for fiber packaging of devices.

Frequently Asked Questions
High power collimators and focusers are used to collimate or focus light exiting a fiber to a desired beam diameter or spot size. They can be used with laser diodes, fiber lasers, acousto-optic modulators, and other fiber optic devices.
OZ Optics' high power collimators and focusers have a rugged and compact design, low insertion loss, low backreflection, wide wavelength range, wide range of beam diameters, and are available in aspheric, plano-convex, C-lens, axial GRIN lenses, and biconvex lenses. They also have singlemode, multimode, polarization maintaining, and large mode area (LMA) fiber versions, and diffraction limited optics. Additionally, they are low cost.
High power collimators and focusers are used for fiber optic device packaging, including wavelength division multiplexors, isolators, splitters, and integrated optics. They are also used for source to fiber coupling, laser marking, and laser machining.
The wavelength range is 200nm to 2100nm, the backreflection is -40 and -60dB, the polarization extinction ratios are 20, 25, or 30dB, the beam diameters range from 0.2 to 22mm, and the spot size can be as small as <5 microns. The wavefront distortion ranges from λ/4 to λ/10.
The collimated beam diameter (BD) and full divergence angle (DA) depend upon the focal length of the lens (f), the core diameter (a), and the fiber numerical aperture (NA). The collimated beam characteristics are given by: BD(mm) = 2 x f(mm) x NA and DA(mrad) = a(µm) / f(mm). However, different definitions for the numerical aperture are used by fiber manufacturers, so OZ Optics uses 1/e2 definitions for its calculations of the beam diameter wherever possible.
