Automatic Adjustment of Fiber Optic Collimator
The autocollimator is a very sensitive angle measuring device and is thus used for the precise angular adjustment of optical or machine components. Due to the collimated beam (infinity adjustment) the measurement results are independent from the distance to the object under. Thorlabs offers a variety of fiber collimation and coupling solutions. FiberPorts can be used to provide a stable platform for coupling light into and out of FC/PC, FC/APC, or SMA terminated fiber with five or six directional adjustments. This article delves into the principles, applications, and benefits of using auto-collimators for optical assemblies. Via the collimator functionality, the structure engraved on the reticle is imaged to infinity. The device under test is placed in the optical path and reflects the light back into the. When do you need a separate micro focus optics? For spots < 10 times the mode field MFD of the fiber, a good quality spot can no longer be achieved by simply refocusing the collimation optics.
