LightPath 355230 | 633nm Alignment, 0.55 NA Fiber Collimator w/ SMA Connector

Product Details Easy to Integrate Models for FC/PC, FC/APC, and SMA Connections Available Four Wavelength Ranges Covering 350-1600nm LightPath Fiber Optic Collimators are designed to collimate light exiting a fiber to a desired beam diameter or spot size or to focus light into a fiber when used in reverse. 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. LightPath Fiber Optic Collimators 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 and pigtailed receptacles, as well as communications and data transfer.
