Description
The Ø 4.5 mm aperture can be attached to Fiber Collimators of series 60FC-L and 60FC-T with an outer diameter Ø 25 mm in order to narrow down the collimated beam.
Please note: In case of use with a single-mode / PM-fiber, the Gaussian beam from the fiber collimator is truncated by the aperture.
