Fiber optic collimators are used to either coupling light from free space into an optical fiber or collimating light from a fiber to form a collimated (parallel) optical beam. Fiber collimators are key components with numerous applications. For example, in spectroscopy, a fiber collimator can collect light in a narrow field of view into a fiber which is in turn connected to a spectrometer. In another example one fiber collimator is connected to a light source and the collimated beam passes through a cuvette. On the other side of cuvette a second fiber collimator collects light and sends it to the spectrometer.

To maximize transmission wavelength range Mightex fiber collimators feature a single BK7 lens without optical coating. In the UV collimators, a UV fused silica lens is used instead. The collimators have a stainless housing for maximum durability. Fiber patchcords with fiber core diameter of up to 1500µm can be connected to the fiber collimator through the SMA connector. The M12x0.5 external thread or the 13mm-diameter barrel can be used to mount the fiber collimators in a system setup.


The full field of view (FOV) or full divergence angle can be calculated as FOV = 2atan(D/2f) where D is the fiber core diameter and f is the focal length of the lens. Alternatively, the linear field of view on an object placed a distance L away from the collimator is D(L/f).
