350~5000nm fiber end face collimator/coupler
   
  Compact, ultra-stable fiber end collimators/couplers are user-friendly devices for optical coupling or output light collimation. Each unit incorporates an achromatic or aspherical lens with an effective focal range of 2.0-18.4 mm, featuring FC/PC, FC/APC, or SMA fiber connectors. For applications requiring short effective focal lengths (≤7.5 mm), we provide collimators/couplers with FC connectors compatible with both FC/PC and FC/APC interfaces. Their five-axis adjustment system works in tandem with short focal lengths, ensuring negligible sensitivity to off-axis inputs.
   
  Feature:
    	- Super stable micro positioning alignment with five degrees of freedom plus rotation adjustment
  	- Delayed and scarce
  	- FC/PC and FC/APC versions are compatible with 2.1 mm wide key and 2.0 mm narrow key joints, SMA collimator/coupler for SMA905 joints
  	- Use aspherical or achromatic lenses
  	- Suitable for single mode (SM), multi mode (MM) and polarization maintaining (PM) optical fibers
  	- The film enhancement options include visible, near-infrared and mid-infrared wavelength ranges
  	- Effective focal length 2.0~18.4mm
