Edmund Optics Inc. 0.25 NA Fiber Collimator w/ SMA Connector, 543nm Alignment NT47-221

Easy to Integrate Models for FC and SMA Connections Available Three Wavelength Ranges Covering 350-1600nm These components are designed to collimate/focus light exiting a fiber to a desired beam diameter or spot size. The lenses are diffraction limited, so they can achieve spot sizes down to a few microns. Lenses also feature an antireflection coating for low back reflection. These units are designed so that they can be used in pairs to couple the input and output light of optical devices. Optimum performance for long-term use is ensured by the factory set and tested lens alignment. Typical applications can include use with fiber coupled lasers, pigtailed receptacles, etc.
