Feb 16, 2009 Designed to collimate or focus light exiting optical fiber to desired beam diameter, collimators can be used with laser diodes, photodiodes, acoustic-optic modulators, and other fiber optic devices. They come in 3 sizes: macro collimator for optical fiber core sizes over 800 µm dia, mid-size collimator for sizes up to 800 µm dia, and micro collimator for fibers up to 400 µm dia. Also available, focus guides thread into macro and mid-size collimators to refocus beam at given distance.
