Product configurator


The a|AspheriColl is an adjustable fiber collimation device, which enables the perfect connection of FC/PC patch fibers to your set-up. Combine the world’s smartest off-the-shelf fiber collimator for NAs up to 0.275 with BeamTuning or other beam shaping elements to obtain any desired output beam while maintaining a diffraction-limited wavefront.

  • Fiber collimator covering for NAs up to 0.275
  • Focal length: f = 20mm, with Øe 11.5mm
  • Optimized for wavelength range 355nm - 1600nm
  • Simplified wavelength adaption by setting adjustment unitwith SW2 allen key
  • Perfectly aligned lateral position
  • Completely diffraction-limited performance (Strehl > 0.95) when used with FC/PC patch fibers
  • Thanks to matching adapters also usable for APC fibers
  • No truncation effects compared to other available fiber couplers
  • Thanks to bigger output beam diameters, no additional expansion might be needed (shorter system length)
  • Laser induced damage threshold (Coating): 12J/cm², 100Hz, 6ns, 532nm
