The a|AspheriColl is an adjustable fiber collimation package and the latest addition of the BeamTuning product range. Combining this element with a|BeamExpanders generates any desired output beam diameter while maintaining a diffraction-limited wavefront.

Key Benefits
= Flexible choice of output beam diameter in combination with BeamExpanders
= Simple mounting to BeamExpanders via metric fine thread
= Always perfectly aligned lateral position
= Completely diffraction-limited performance (Strehl > 0.95) when used with FC/PC patch fibers – individually measured and guaranteed by an original asphericon certificate
= Optimized for a wavelength range from 500 nm to 1600 nm
