Collimators and Focus Guides for Fibre Optics

Optical fibre manufacturer Fiberguide, part of the Halma technology group, has introduced a line of standard collimators and focus guides for use with a wide variety of optical systems.

Designed to collimate or focus light exiting an optical fibre to a desired beam diameter, the collimators can be used with laser diodes, photodiodes, acoustic-optic modulators and other fibre optic devices. Focus guides thread into the collimator, refocusing the beam at a given distance. Collimators and focus guides can be used as matched pairs to couple light in and out of optical devices.

The rugged modules are manufactured to accept SMA, ST, FC, or machined ferrule-style connectors. Assembled and pre-set to meet required specifications, all collimators and focus guides can be adjusted to provide flexibility.

Collimators are available in three sizes: the macro collimator for optical fibre core sizes larger than 800µm diameter, the mid-size collimator for sizes up to 800µm diameter, and the micro collimators for fibres up to 400µm diameter. Focus guides are available for the macro and mid-size collimators.
